Hi all!

We have installed a set of 3 CPS (in three different sites) to configure IO fencing. We wonder how many clusters can use this set of 3 CPS. In the doc "Veritas™ Cluster Server Administrator's Guide 6.0", I read:

- 128 clusters.... of how many nodes?? 2,3,...???

In this post http://www.symantec.com/connect/forums/single-cps-use-multiple-clusters , AHerr says that "in testing we have had over 1000 2-node clusters using the same set of 3 CPS nodes". Why the limitation of 128 clusters????

Other question is about the bbdd /etc/VRTScps/db/current/cps_db, what happens if this file is deleted by accident??? Is it correct to use the cps_db file of the others CPS??? (I tried and worked fine) should we backup it up daily???

Regards,

Joaquín

Some business environments may require a cluster setup that supports application high availability with differentiated configurations in the same cluster. For example, some applications in the cluster may need high availability with or without dependency on databases. And, some applications may require high availability with support for clustered databases. In such scenarios, you may want to consider a mixed configuration of Storage Foundation for Oracle RAC (SF Oracle RAC) and Storage Foundation Cluster File System High Availability (SFCFSHA) in your environment.

In mixed configurations, nodes with applications that require high availability can be configured to run SFCFSHA while nodes with applications that require clustered databases can be configured to run SF Oracle RAC.

This article introduces the configuration scenarios and the advantage of having mixed configurations.

The deployment scenarios are as follows:

• Scenario 1: SF Oracle RAC is installed on all nodes in the cluster. Some of the nodes in the cluster are used to run applications in SFCFSHA environment.
• Scenario2: SFCFSHA is installed on all nodes in the cluster. Some of the nodes in the cluster are used to run SF Oracle RAC.

Both configuration scenarios provide the following advantages:

• Optimize and extend your cluster infrastructure to suit application needs in your environment.
• Repurpose nodes in a cluster. A node running SFCFSHA can be reconfigured to run SF Oracle RAC.
• Manage application dependencies.
• Back up Oracle RAC database from SFCFSHA nodes in the cluster.
• Enhanced storage availability with Cluster Volume Manager (CVM)  I/O shipping.

For more information and instructions:

Setting up a mixed configuration cluster running SF Oracle RAC and SFCFSHA

Additional information can be obtained from the following documents on SORT:

Hello folks ,

     Is there any way to disable the IO Fencing in VCS 5.1 Cluster without bringing the cluster down. I have a cluster consisting of 8 nodes , when I tried to add another node , Problems happened and the Fencing keys got corrupted. Therefore , I need to disable the IO fencing as it is not needed as I do not have CVM or CFS.

Thanks

Hi, we have problems with VCS (version 5.1) cluster on MS Exchange 2003 after we have updated AD to 2008 r2.

Situation is very odd, because we have another VCS cluster on MS Exchange 2003 (all versions are same) working fine.

Here is Lanman log:

On fresh install of SFHA 6.0.3 on Solaris 11.1 SPARC (per instructions, ie: install 6.0.1 w/out configuration, install 6.0.3, then configure) - the following service is showing in maintenance state:

# svcs -xv
svc:/system/VRTSperl-runonce:default (?)
 State: maintenance since Mon Feb 11 14:11:28 2013
Reason: Start method failed repeatedly, last exited with status 127.
   See: http://support.oracle.com/msg/SMF-8000-KS
   See: /var/svc/log/system-VRTSperl-runonce:default.log
Impact: This service is not running.

Looking at the log, the start method fails as the file it's trying to run ( /opt/VRTSperl/bin/runonce ) is missing / does not exist:

# tail /var/svc/log/system-VRTSperl-runonce:default.log
[ Feb 11 14:11:28 Executing start method ("/opt/VRTSperl/bin/runonce"). ]
/usr/sbin/sh[1]: exec: /opt/VRTSperl/bin/runonce: not found
[ Feb 11 14:11:28 Method "start" exited with status 127. ]
[ Feb 11 14:11:28 Executing start method ("/opt/VRTSperl/bin/runonce"). ]

/usr/sbin/sh[1]: exec: /opt/VRTSperl/bin/runonce: not found
[ Feb 11 14:11:28 Method "start" exited with status 127. ]

Has anyone else seen this in SF 6.0.3?

The file name implies it's something that only needs to be run once (and was possibly deleted after it was run) - should this service be disabled/removed as part of the installation so it doesn't come up in maintenance every time?

Please advise if further details are required.

thanks,
Grace

Storage Foundation Cluster File System (CFS) provides several advantages over a traditional file system  when running in a VMware guest OS.  The primary benefit is that multiple virtual servers (up to 64) using CFS can simultaneously access data residing on the same physical LUN or virtual disk.  A secondary advantage is the ability to provide faster application failover within virtual servers than a VM restart allows.  And by using the VMware hypervisor to manage the virtual servers and their resources, applications gain all the advantages of running in a virtualized environment.

Utilizing CFS, an application can be recovered in a few seconds when running in a virtual machine (VM). The CFS High Availability Module will detect outages instantly and CFS will provide immediate access to the application data in another VM.  Since the application is already running in another VM with access to the same data, no additional time is required to map the storage to a new VM and the application can immediately begin accessing the data needed to recover the service. Because several VMs can have simultaneous access to the data, other activities like reporting, testing, backup, etc… can be implemented without incurring in any CPU overhead on the primary application VM.

Business Intelligence applications are another area where a robust cluster file system can provide scale-out capabilities. Sharing the same data across all the virtual servers minimizes storage consumption by avoiding duplicate copies of data. By making the data immediately accessible for processing across all the servers, data processing and transformation cycles can be reduced.

Finally, CFS can provide a framework for an adaptable grid infrastructure based on virtual machines. With the CFS cluster capability to add/remove nodes dynamically without bringing the cluster down, administrators can tailor the cluster size to the changing dynamics of the workload.  The cost of managing such a grid can be reduced using CFS storage optimization features such as compression, de-duplication, snapshots, and thin provisioning.

Cluster File System connection to storage can be implemented in two ways on VMware, depending on the application requirements:

Support for both options is documented in Using Veritas Cluster File System (CFS) in VMware virtualized environments.

Each approach has its own pros and cons. RDM-P provides a direct connection between the virtual machine file system and the underlying physical LUN. Because of this, applications will likely achieve higher performance vs. a VMFS connection. Additionally, disk-based SCSI-3 data fencing  can be implemented for data protection and it is possible to create a cluster or both physical and virtual machines. The downside of using RDM-P is that is does not allow the hypervisor  to perform VMware management activities such as vSphere vMotion.

A VMFS virtual disk (VMDK) architecture can provide a more flexible model for managing storage, i.e. cluster nodes can be dynamically moved across ESX servers, allowing sever maintenance while keeping all cluster nodes attached to the shared data.   Normally, in order to prevent data corruption, VMFS prevents access by more than one VM at a time to a VMDK.   In order to allow CFS to provide simultaneous access to the virtual disk(s) by all the nodes in the cluster, the VMFS multi-writer flag must be enabled on the VMDK.  The HOWTO8299 document mentioned above provides detailed instruction regarding this. It should be noted that applications can expect slightly lower performance when using VMFS vs. RDM-P, due to VMFS overhead.  Additionally, VMware virtual disks do not emulate the SCSI-3 PGR data fencing command set at this time, so extra precaution should be taken to prevent inadvertent mapping of cluster VMDK to non-cluster virtual machines.

A detailed explanation on how to install and configure CFS with VMDK files can be found in the Storage Foundation Cluster File System HA on VMware VMDK Deployment Guide, which is attached to this article. This deployment guide presents a very specific example using the following infrastructure:

• RedHat Enterprise Linux 6.2
• Storage Foundation Cluster File System HA 6.0.1
• ESXi 5.1

A four nodes cluster will be created using two different ESX servers as shown in this diagram:

This guide is not a replacement for any other guide (VMware or otherwise), nor does it contain an explicit supportability matrix. It is intended to document a particular implementation that may help users in their first implementation of CFS in a VMware environment using VMFS virtual disks as the backend storage. Please refer to product release notes, admin, and install guides for further information.

Hi,

Would just like to know if the following solutions can be implemented via cloud? SF, VCS, VVR, VOM and APPHA. A client has their own private cloud and wants to create their DR via cloud as well. They are looking at our solution to help them implement their DR.

Many Thanks!

Dan

We have 2 Sun 3510 arrays each containing three disks. VxVM, on Solaris 10 for SPARC, has been set up to mirror each disk, ie Array 1 Disk 1 is mirrored to Array 2 Disk 1 etc etc. We had a problem with the power to the controller of array 2 and the disks in that array ended up in a disabled and removed state.

The power has now been restored and the disks are now visible to the operating system again. However whatever we try we can not get VxVM to accept the disks.

It can see them but will not re-add them. We have followed the replace disk procedure which fails with the message 'no device available to replace'.

Any suggestions would be most gratefuly received.

What is the use of service gp in cluster?

What if i dont create it?

I suspect that defragging a VxFS file system on a VVR volume would result in LOTS of traffic on the link and lots of blocks requiring sync?

This would risk filling up the SRL and generate lots of sync traffic. Anyone try this or has any insight on this?

The Cluster Manager (Java Console) enables you to administer your cluster. You can use the different views in the Cluster Manager (Java Console) to monitor and manage clusters and Veritas Cluster Server (VCS) objects, including service groups, systems, resources, and resource types.

If you want to manage clusters using the Cluster Manager (Java Console), the latest version is available for download from http://go.symantec.com/vcsm_download.

You need a free SymAccount to download the Cluster Manager (Java Console). You can obtain a SymAccount at: https://symaccount.symantec.com/SymAccount/index.jsp.

You cannot use the Cluster Manager (Java Console) to manage new features in Veritas Storage Foundation and High Availability releases 6.0 and later, for example, the Virtual Business Service (VBS) feature, using the Cluster Manager (Java Console). The Veritas Cluster Server Management Console is deprecated. Symantec recommends using Veritas Operations Manager instead to manage Storage Foundation and Cluster Server environments.

Veritas Operations Manager provides a centralized management console for Veritas Storage Foundation and High Availability products. You can use Veritas Operations Manager to monitor, visualize, and manage storage resources and generate reports.

You can download Veritas Operations Manager at http://go.symantec.com/vom.

Hi,

I need some help with VxVM volumes

I have been requested to restore some data from disks in a volume group

This was how it looked like before

v  lvol4a       -            ENABLED  ACTIVE   2537355264 ROUND   -        gen
pl lvol4a-01    lvol4a       ENABLED  ACTIVE   2537355264 CONCAT  -        RW
sd disk32-01    lvol4a-01    disk32   0        1006534400 0       xiv0_38  ENA
sd disk33-01    lvol4a-01    disk33   0        1006534400 1006534400 xiv0_39 ENA
sd disk35-01    lvol4a-01    disk35   0        524286464 2013068800 xiv0_42 ENA
pl lvol4a-02    lvol4a       ENABLED  ACTIVE   2537355264 CONCAT  -        RW
sd TMP1-01   lvol4a-02    TMP1  0        1019148544 0       xiv0_40  ENA
sd TMP2-01   lvol4a-02    TMP2  0        1308491520 1019148544 xiv0_41 ENA
sd TMP1-02   lvol4a-02    TMP1  1019148544 209715200 2327640064 xiv0_40 ENA
 

Then the volume was deleted as below

vxedit -g DISKGROUP001  -rf rm  lvol4a

And recreated with same name and plex

vxmake -g DISKGROUP001 vol lvol4a plex=lvol4a-01
 

Now it looks like this..

v  lvol4a       -            ENABLED  ACTIVE   2537355264 ROUND   -        gen
pl lvol4a-01    lvol4a       ENABLED  ACTIVE   2537355264 CONCAT  -        RW
sd disk32-01    lvol4a-01    disk32   0        1006534400 0       xiv0_38  ENA
sd disk33-01    lvol4a-01    disk33   0        1006534400 1006534400 xiv0_39 ENA
sd disk35-01    lvol4a-01    disk35   0        524286464 2013068800 xiv0_42 ENA

 Now I need to mount the data from these disks. which are siting the the VG and are not associated anywhere

disk01      auto:cdsdisk    TMP1      DISKGROUP001  online
disk02      auto:cdsdisk    TMP2      DISKGROUP001  online

 So

1> has there been any loss data as a result of deleting and recreating volume  lvol4a

2> If there is no data loss can I have the below as a spererate volume (vol_tmp) and mount the volume 2 )

 pl lvol4a-02    lvol4a       ENABLED  ACTIVE   2537355264 CONCAT  -        RW
sd TMP1-01   lvol4a-02    TMP1  0        1019148544 0       xiv0_40  ENA
sd TMP2-01   lvol4a-02    TMP2  0        1308491520 1019148544 xiv0_41 ENA
sd TMP1-02   lvol4a-02    TMP1  1019148544 209715200 2327640064 xiv0_40 ENA
 

they dont exist in the VG only below dm exists 

dm TMP1      disk01      auto     65536    1274937088 -
dm TMP2      disk02      auto     65536    1308491520 -
