Vxdisk shows disk error on secondary cluster

Such a behaviour is observed in case of EMC Mirrorview technology.

Hi,

If you are using EMC Mirroeview than the disk son the secondary site show as error in VxVM. The diskgroup will be imported correctly when the replication role is changed from secondary to primar when you try to bring the service group online on the DR site.

Were these disk in a different state before? Do u have anyother cluster with similar configurations showing a different disk state?

Sudhir

Hi ,

I am still loking for some help

Which array based replication are you using?

Sudhir

Hello,

about vxprint, you are not getting outputs on secondary because diskgroup is deported ... so that is normal

secondly, this doesn't looks to be a A/A cluster, as your secondary site is idle, it will takeover if some failure happens or someone forces secondary to be active .

Now about the errors you are getting,

1. Paste the exact error messages here

2. What is the version of OS & VxVM ?

3. I am assuming your replication is VVR here ? or something else ?

4. Have you made sure that disks which are giving errors on secondary are indeed part of the replicated data set from primary ? are there any additional disks in system which are not participating in replication ?

Also, I see that this post was posted in "Storage & clustering documentation",  I have moved it to "Storage Foundation" forum so that others can see & contribute

Hello ,

As Sudhir Mentioned we are using EMC Mirrorview technology and not VVR. 

ok i agree for vxprint not showing any results. I am not fully sure if the disk with errors is a part of data replication set , but i assume yes if i see the disk will typically form  critical disk groups when cluster will be made online

What is the version of ASLAPM in use ?

# pkginfo -l VRTSaslapm

seems like linux had some issues with lvm headers which was fixed in hotfix, worth to find if something similar in Solaris was discovered

Hi ,

To Answer @Sudhir : I am really not sure as i have been given responsibility of this recently ,and this is the only global cluster setup we have.

You might be true with the "linux article"  but what surprises me is that the disks cannot be seen at OS layer too . PFB .
