Unable to activate my non-root vg

[john123]

Check with storage team whether they have masked any luns from the server in the storage side.?or for any fabric outage and also check for any HBA hardware changes done in server..

Mean while which model of storage u r using is it Symmetrix or clarion?

Well, John. This has happened just after patching the server. So, I really dont think storage team would have masked the LUNs.

Is there any configuration need to be checked as the patching would have changed them.

It is EMC clarion.

If dd fails then lvm commands also will not reveal any info.. Does pvdisplay or diskinfo provide any details for /dev/rdsk/c12t0d6 ?

would it be possible to export one vg and import it for testing?

However we should get clarified from storage team why dd is failed to read the disk before we try anything..because dd is the lower disk level read. If this fails lvm also will not be able to read the disks.

You should do nothing at LVM level for the moment. dd is enough : we know there is physical problem.

Cout you post (in attachment please) a full ioscan -fn (that is without -k or -u). The objective is to see if hardware path to EMC storage has changed : maybe SAN team has modified some parameters that deal with HP-UX 11iv2 hardware path ?

Thanks Guys. This is resolved now.

I did a powermt display and found some dead paths which are not related with my current configuration. SO, I did a powermt check and removed them.Then, did a powermt config and save.

Now I am able to activate my other vg's.
