HP-UX VxVM and EVA Continuous Access (CA)

[Thomas Vogt (CH)]

Hi all

We try to failover a Veritas VxVM Disk to another EVA storage using Continuous Access (CA).

Environment:
- 2 server (BL860c) running HP-UX 11.31, ServiceGuard 11.18
- Shared disks (Veritas cluster FS (CFS) on Veritas VxVM with DMP multipathing)

If we present the LUN on the failover EVA to the servers and do a path rescan (ioscan -fnC disk), HP-UX can see the additional paths to the disk.

My question now, what do I have to configure for presenting the new paths to the Veritas VxVM disk group?

And is it actually possible to use CA together with DMP multipathed VxVM disks?

Thank you very much in advance.
- Thomas

Hi Thomas,
Please run the command vxdctl enable on the host
This will make Weritas Vomume Manager recognise the new disk.

Then run vxdisk list to find the new disk and then add the disk to any VG you need.


You shpuld be able to CA with VXDMP.
SInce CA is use for data replicatin and this is done on the storgae. Where is VXDMP is used as the multipath Software on the Server side.

Hope this helps
