On a two-host cluster, if you chose no for Quorum Auto Configuration in the input_otp.dat file, you must manually select and configure the quorum disk as described in this procedure.
The following substeps apply only to a two-host cluster. If you are setting up a three-host or more clustered Sun OTP system, this procedure is optional.
Open a separate terminal window and log in as root to the first Sun OTP host.
Type the following command to display the cluster disk information.
/usr/cluster/bin/cldev list -v
DID Device Full Device Path d1 pcl44-otp1:/dev/rdsk/c0t8d0 d1 pcl44-otp2:/dev/rdsk/c1t8d0 d2 pcl44-otp1:/dev/rdsk/c0t9d0 d2 pcl44-otp2:/dev/rdsk/c1t9d0 d3 pcl44-otp1:/dev/rdsk/c1t10d0 d4 pcl44-otp1:/dev/rdsk/c1t11d0 d4 pcl44-otp2:/dev/rdsk/c0t11d0 d5 pcl44-otp1:/dev/rdsk/c2t1d0 d6 pcl44-otp1:/dev/rdsk/c2t3d0 d7 pcl44-otp1:/dev/rdsk/c3t0d0 d9 pcl44-otp2:/dev/rdsk/c2t3d0 d10 pcl44-otp2:/dev/rdsk/c3t0d0 |
In the above example, disks d1 and d2 are shared by both hosts of the two-host cluster. The quorum disk must be a shared disk.
Configure a quorum disk.
/usr/cluster/bin/clq add shared disk ID
Where shared disk ID is a shared disk ID.
For example, to configure d4 as a quorum disk, type the following command.
/usr/cluster/bin/clq add d4
Reset the two-host cluster to normal mode.
/usr/cluster/bin/clq reset
