diskgroup import from another system

[Assaf_Leibovitc]

Hi,

We have a system with a diskgroup, dg1.

We have another site running with the same configuration and is used for disaster recovery.

We are trying to import a diskgroup after using EMC's MirrorView to replicate the disks in LUN level.

When we bring the disks back, VxVM sees them with udid_mismatch , we handle this with:

"vxdisk clearimport" and "vxdisk updateudid"

When trying to import the disk group we get the error that another host is using them... the dgid is the key here as it is with the info of the other host.

we are able to workaround it, we backup the dg configuration just before running the replication, and we restore it after the disks are brought back to the system , is there a cleaner way to do that?

(vxdg -C import didn't seem to work...)

Thanks

You don't mention any versions.

But this sounds like a case I worked recently:

you need 5.0MP1 RP1

Incidents from 5.0 MP1 + 597517 + 936419  
VxVM 5.0 MP1 Rolling Patch 1 (124361-01)
VxVM 5.0 MP1
Solaris 8,9,10

Hi,

Thanks for the reply,

We use Storage Foundation 5.0 above Solaris 10 11/06 , Sparc.

Can you describe what is the behaviour after the patch installation?

What commands did you use?

Thanks

Hi,

You have to install the RP1

From the Reamdme-File:

"(e936419)  vxdisk updateudid after udid_mismatch could lead to dg config mess up"

Be carefull with using updateudid while importing the diskgroup without the patch. I had the same problem and a diskgroup get damaged.
