Oracle Data Base Replication with VVR under SFCFSHA/DR
Hi All; we are looking for whether VVR can use for the oracle database replication instead of oracle data guard solution. If it is used, do you know veritas gives support for any problem faced. even VVR keeps the write order fidelity, it is not certain the database integrity will ve preserved at the disaster site. do you have any best practices and white papers, experience, anything you suggest for this deploymeny?
upgrade Storage Foundation and VCS 4.1 to SFHA 6.X
HI All, I'm going to upgrade my production environment with VXVM,VXFS and VCS 4.1. My question are: 1) After upgrade to Solaris10 up11, it's possibile to remove all Veritas packages and reinstalling everything at version SFHA 6.1 (and recover vcs configuration)? Does it support? 2) I see from Admin Guide this extract: Currently, only the Version 7, 8, 9, and 10 disk layouts can be created and mounted. The Version 6 disk layout can be mounted, but only for upgrading to a supported version what does it mean? Thanks in advance Rick
SFRAC 6.1 on Solaris 10 Supportability
I have a customer who is upgrading a critical SFRAC cluster with global apps and has a question about the supportability of 6.1 Sol 10 with u8 base. Our documentation states that that 6.1 is compatible with Sol 10 update 9 onward. Does this mean a Sol 10 U9 BASE build or a kernel patch that serves u9 and higher? Their current nodes are running a base Sol10 U8 build but will be patched to get to ~u11 release…but the base still remains u8…if referring to the /etc/release file. Need some clarification on this as soon as possible. Thank you!
Sharing a SFHA/CFS filesystem between Physical and VM servers
Hello, and good afternoon to you all. For one of our cluster deployments, we've been requested to create a Cluster Shared Filesystem including 9 physical servers and 3 VMware VMs (vSphere 5.0 or 5.5, if this matters), all running RHEL6.5. The VMs would be using RDM-P and adhering to all the CFS-inside-a-VM stuff, as always. Performance and sizing issues aside, is this a supported configuration for SFCFSHA? I know using this for VCS is fully supported (and even advertised), but I can't seem to find the mention to this on CFS mounts. Thanks for the attention
detaching vmdk files on vmware vm
When the application failover happens in VMware Guest enviorments, the VCS is responsible for failing over the application to other vm/vcs node on diffrent ESX host. In a scenario where the ESX/ESXi host itself faults, the VCS agents begin to fail over the application to the failover target system that resides on another host. The VMwareDisks agent communicates with the new ESX/ESXi host and initiates a disk detach operation on the faulted virtual machine. The agent then attaches the disk to the new failover target virtual machine. In this senario, how are the stale i/o from failing over guest/ESX host avoided? Are we on the mercy of VMware to take care of it? With SCSI3 PR this was the main problem that was solved. Moreover in such senario's even a garceful online detach wouldnt have gone through. I didnt find any references on VMware discussions forums as well. My customer wants to know about it, before he can deploy the application. Thanks, Raf
SFRAC Certification with Oracle RAC in Solaris Zones
IHAC that is utilizing Oracle RAC 11 in Solaris Zones and has advised us that Oracle do not support SFRAC in this environment. If fact they claim it is incompatible. Can someone please advise where I can find: - 1) Our SFRAC Certification documentation SF 5 or 6. 2) Documentation from Oracle that advises that SFRAC is certified for the Solaris Zone platform. 3) Whitepapers/Case studies/ blogs etc. that we could reference for this environment. 4) Any other information you can provide. Many thanks Regards Brian
NFS agent for CFS share
Dear All, I have setup CFSshare. I can see under cfsshare display, but if I run "cfsshare share /emm2 rw" is NOT sharing but from the Java Console of the cluster. The NFS resource has got a question MARK. So I am really not too what to do now., root@node_1# cfsmount /emm5 rw Mounting...

The vxcdsconvert command makes disks and disk groups portable between systems running VxVM with the Cross-platform Data Sharing (CDS) feature. For more information on the CDS feature, see: Overview of the CDS feature Setting up your system to use CDS You can resize the CDS disks to larger than 1 TB. For more information, see: Dynamic LUN expansion You can use the vxcdsconvert command to: Check whether disks and disk groups can be made portable (using the –A option). Convert disks and disk groups to be CDS-compatible. For more information on the conversion procedure, see: Converting non-CDS disks to CDS disks Converting a non-CDS disk group to a CDS disk group Note the following points: The vxcdsconvert command requires that disk groups be version 110 or greater. When a disk group is made portable, all disks within the disk group are also converted. Converting a disk group that contains RAID-5 volumes and logs fails, if there is insufficient space in the disk group to create an additional temporary RAID-5 log. The default private region size increased from 512 KB to 1 MB in SFHA release 3.2, and from 1 MB to 32 MB in release 5.0. vxcdsconvert (1M) 6.0.1 manual pages: AIX HP-UX Linux Solaris VxVM documentation for other platforms and releases can be found on the SORT website.SFHA Solutions 6.0.1: Using Veritas Operations Manager Package Anomaly Add-on to find package installation anomalies
