Create the BOOT-MIR mirrorset using disks 30200 and 30300 and the
2
CROOT-MIR mirrorset using disks 40000 and 40100.
Initialize the BOOT-MIR and CROOT-MIR mirrorsets. If you want to set
3
any initialization switches, you must do so in this step. The BOOT-MIR
mirrorset will be used for the Tru64 UNIX and cluster member system
boot disks. The CROOT-MIR mirrorset will be used for the cluster root
(/), cluster /usr and cluster /var file systems, and the quorum disk.
Verify the mirrorset configuration and switches. Ensure that the
4
mirrorsets use the correct disks.
Create appropriately sized partitions in the BOOT-MIR mirrorset using
5
the percentage of the storageset that each partition will use. These
partitions will be used for the two member system boot disks (25 percent
or 1 GB each) and the Tru64 UNIX disk. For the last partition, the
controller assigns the largest free space available to the partition (which
will be close to 50 percent or 2 GB).
Create appropriate sized partitions in the CROOT-MIR mirrorset using
6
the percentage of the storageset that each partition will use. These
partitions will be used for the quorum disk (5 percent), cluster root
partition (15 percent), /usr (40 percent), and /var file systems. For
the last partition, /var, the controller assigns the largest free space
available to the partition (which will be close to 40 percent). See the
TruCluster Server Software Installation manual to obtain partition
sizes.
Verify the BOOT-MIR mirrorset partitions. Ensure that the partitions
7
are of the desired size. The partition number is in the first column,
followed by the partition size and starting block.
Partition for member system 1 boot disk.
8
Partition for member system 2 boot disk.
9
Partition for Tru64 UNIX operating system disk.
10
Verify the CROOT-MIR mirrorset partitions. Ensure that the partitions
11
are of the desired size. The partition number is in the first column,
followed by the partition size and starting block.
Partition for the quorum disk.
12
Partition for cluster root (/) filesystem.
13
Partition for cluster /usr filesystem.
14
Partition for cluster /var filesystem.
