Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

To remove and replace a failed disk
1
Use the vxdiskadm utility to remove the failed disk from the disk group.
Refer to the Veritas Volume Manager Administrator’s Guide.
2
Add a new disk to the node, initialize it, and add it to the coordinator disk
group.
See the Veritas Storage Foundation for Oracle RAC Installation and
Configuration Guide for instructions to initialize disks for I/O fencing and to
set up coordinator disk groups.
If necessary, start the disk group.
See the Veritas Volume Manager Administrator’s Guide for instructions to
start the disk group.
3
Retest the disk group.
See “Testing the coordinator disk group using vxfentsthdw -c option”
on page 109.
Performing non-destructive testing on the disks using the -r
option
You can perform non-destructive testing on the disk devices when you want to
preserve the data.
To perform non-destructive testing on disks
◆
To test disk devices containing data you want to preserve, you can use the -r
option with the -m, -f, or -g options.
For example, to use the -m option and the -r option, you can run the utility
as follows:
# vxfentsthdw -rm
When invoked with the -r option, the utility does not use tests that write to
the disks. Therefore, it does not test the disks for all of the usual conditions
of use.
Testing the shared disks using the vxfentsthdw -m option
Review the procedure to test the shared disks. By default, the utility uses the -m
option.
This procedure uses the /dev/vx/rdmp/c1t1d0 disk in the steps.
