Maintaining GFS for VTS | 151
Adding a vault to a GFS cluster
Complete the following steps to create a vault in a GFS cluster:
1. Launch a command prompt on a VTS server in the cluster and log in as root.
2. Choose the partition to use. You can view the /etc/fstab file to see the partitions that are
already in use. To view available partitions, enter the following command:
sg_map -x
The following is an example of the output of this command:
/dev/sg0 1 0 3 0 1 /dev/st0
/dev/sg1 10 0 0 0 12
/dev/sg2 10 0 0 1 0 /dev/sda
/dev/sg3 10 0 0 2 0 /dev/sdb
/dev/sg4 10 0 0 3 0 /dev/sdc
/dev/sg5 10 0 0 4 0 /dev/sdd
/dev/sg6 10 0 1 0 12
/dev/sg7 11 0 0 0 12
/dev/sg8 11 0 1 0 12
In this example, /dev/sdd is used on LUN 4.
If you cannot see a new LUN, you can rescan for it by entering this command:
/usr/local/tape/bin/rescan-scsi-bus.sh -l -c -r -w
If you cannot see the LUN after rescanning the SCSI connections, reboot the VTS server.
3. Configuring the partition:
If the vault will be less than 2TB in size, complete the following steps to partition the disk:
a. Enter the following command to partition the device.
fdisk /dev/sde
b. Enter n to add a new partition.
c. Enter p to specify the primary partition.
d. Enter 1 to specify the first partition.
e. Press ENTER to accept the defaults.
f. Enter w to save the configuration.
To confirm the configuration, enter the following command:
fdisk -l /dev/sde
Here is an example of the output:
Disk /dev/sde: 18.4 GB, 18413722112 bytes
255 heads, 63 sectors/track, 2238 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
