Table 3. Shared Volumes
Create the Partitions
When configuring the shared storage device earlier in this document, you created 3 shared volumes.
They are for the cluster lock LUN, the ws package LUN, and the clog package LUN. The cluster lock
LUN can be configured as a “Linux” partition (Hex code 83) and the package LUNs can be
configured as “Linux LVM” partitions (Hex code 8e). Alternatively, you can configure the cluster lock
LUN on a whole LUN starting with the following patches:
SGLX_00330 for Red Hat Enterprise Linux 5 on IA32
SGLX_00331 for Red Hat Enterprise Linux 5 on IA64
SGLX_00332 for Red Hat Enterprise Linux 5 on x86_64
Patches can be downloaded from HP Support Centre at http://www.hp.com/go/hpsc.
If you are using a partitioned LUN for each volume, create a new (n) partition (Partition #1), set the
type (t), and save (w) the settings for the partition.
NOTE: If you are using a whole LUN, skip the steps described below.
The steps in this section are to be executed on one server only.
1. To create a partition on the cluster lock LUN (/dev/sda), run the fdisk command and answer
the prompts as follows (user inputs in bold):
fdisk /dev/sda
Command (m for help): n

e extended
p primary partition (1-4)

Partition number (1-4): 1
First cylinder (1-1024, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-1024, default 1024): 1024
Command (m for help): t

Calling ioctl() to re-read partition table.
Syncing disks.
2. To create a partition on the ws package LUN (/dev/sdb), run the fdisk command and answer
the prompts as follows (user inputs in bold):
fdisk /dev/sdb
Command (m for help): n
