[ Is it possible to use shared storage with different device names during
ASM instance / Disk group creations? ]
ASM Doesn't care what the device names are or if they are even the same
across nodes. Just make sure your disk discovery string in the initASM.ora
file is one that will find the the devices you want it to use. ASM will
interogate the headers of the devices to locate the disks you have allocated
for it to use.

Subject: 10gR2 RAC on AIX shared disk device names issue
Hi,
I am in the process of setting up 2node RAC with the following components:
Oracle 10g R2 RAC
Oracle Clusterware
AIX 5L 5.3
HP Storage
ASM
Following are shared disks for storage:
on Node1:
/dev/rhdisk10 -- for voting disk
/dev/rhdisk11 -- for OCR
/dev/rhdisk12 -- for ASM
/dev/rhdisk13 -- for ASM
/dev/rhdisk14 -- for ASM
on Node2:
/dev/rhdisk10 -- for voting disk
/dev/rhdisk11 -- for OCR
/dev/rhdisk15 -- for ASM
/dev/rhdisk16 -- for ASM
/dev/rhdisk18 -- for ASM
Shared disk names are not same accross my nodes.
we have created new common device name file for non-common disks
dev/rhdisk12-14 & /dev/rhdisk15-18.
new device names are : rac_dsk1, rac_dsk2, rac_dsk3
I am able to access these disks rac_dsk1-3 using dd command.
But Cluster verfication utility fails with error ERROR: /dev/rac_dsk1
Storage operation failed.
I have used the following cluvfy command.
./cluvfy comp ssa -n node1, node2 -s /dev/rac_dsk1,/dev/rac_dsk2
Are there any known issues with cluvfy?
Is it possible to use shared storage with different device names during ASM
instance / Disk group creations?
Thanks
Venkata Giri
