assumption
As per the dmesg this happens when the disk is in readonly mode. but as far as the repstatus shows that we need to diassociate and associate the SRL. If the passthru happens again and again then we need to replace the disk on which SRL is created.
==========================================================
Now the problem is that the disk sdb on which the data volume(data volume name is home) is created show the same message. See below for a reference:

assumption
This happens when the disk is in readonly mode. Why its going in to the "Write Protect is off" mode. Is this the disk problem or something else related with the vxvm
