    I believe you have IOFencing issue here .... that is the reason you are unable to write, & also fencing keys are inconsistent ...

    You can register the keys manually but if possible, have a clean reboot of system after clearing the keys manually ... or atleast restart complete VCS after clearing the keys manually

    so here is what I would say:

    1. clear the IOFencing keys using "vxfenclearpre" command:

    https://sort.symantec.com/public/documents/sf/5.0/solaris/manpages/vcs/vxfenclearpre_1m.html

    2. shutdown all the applications in cluster

    3. shutdown VCS  (hastop -all)

    4. Shutdown Fencing (/etc/init.d/vxfen stop) ... need to run this on both the nodes.

    5. Ensure fencing module is unloaded ( modinfo | grep -i vxfen )

    6. Ensure from gabconfig that only port a exists in all the nodes ( gabconfig -a )

    7. Restart IOFencing on both the nodes (/etc/init.d/vxfen start)

    8. Start cluster one by one on both the nodes (hastart)

    Above procedure should help clear the keys & you should get the access back to the disk ...

Hi Kishore,

you had a chance to look in this ?

 

error state appears on a disk when volume manager is unable to read the label/disk geometry from the disk.. so the reason could be:

1. disk label has been lost

2. disk was replaced & new disk in place

If disk was in use & something happened to private region where vxvm is unable to read the disk private region, in this case, you should see disk going in "failed was" state in vxdisk list ..

In most of the case, you need to a bottoms up analysis & find what happened underneath to the disk .
