Verifying that the nodes have access to the same disk
Before you test the disks that you plan to use as shared data storage or as coordinator disks using the vxfentsthdw utility, you must verify that the systems see the same disk.
To verify that the nodes have access to the same disk
Verify the connection of the shared storage for data to two of the nodes on which you installed SF Oracle RAC.
Ensure that both nodes are connected to the same disk during the testing. Use the vxfenadm command to verify the disk serial number.
vxfenadm -i diskpath
Refer to the vxfenadm (1M) manual page.
For example, an EMC disk is accessible by the /dev/rdsk/c1t1d0s2 path on node A and the /dev/rdsk/c2t1d0s2 path on node B.
From node A, enter:
vxfenadm -i /dev/rdsk/c1t1d0s2
Vendor id : EMC
Product id : SYMMETRIX
Revision : 5567
Serial Number : 42031000a
The same serial number information should appear when you enter the equivalent command on node B using the /dev/rdsk/c2t1d0s2 path.
On a disk from another manufacturer, Hitachi Data Systems, the output is different and may resemble:
# vxfenadm -i /dev/rdsk/c3t1d2s2
Vendor id : HITACHI
Product id : OPEN-3 -SUN
Revision : 0117
Serial Number : 0401EB6F0002
