Hi list,
We currently have a 4 node Oracle RAC on HP UX Superdom Itanimum II with EMC
SAN (Symatrix DMX4) storage. Since few days, we are facing an abnormal
situation where the RAW disks permissions (includes OCR, Voting and ASM
disks) are getting changed dynamically and sometime during the node reboot
too, which cause Cluster hung situation. Our current workaround is to reset
the permissions to RAW disks.
If I am not wrong, this sort of problem exists on Linux reboot and to
prevent this, we need to set a parameter which keeps the existing parameter
alive. I am not sure this is the same case on HP. Does anyone out there has
faced similar kind of issue? or it is very abnormal situation?
We did open a call with HP support and they said, basically, OS doesn't have
any control on the RAW devices and definately it won't change the permission
either dynamically or during the reboot time and they suspect Oracle might
be doing something to change the permission.
I have opened a TAR with Oracle too and waiting for the reply. Appreciate if
someone can put some limelight on this issue.
