HP XP10000, XP128 manual Configure disk array devices

Configure disk array devices

Disk arrays are configured using the same procedure for configuring any new disk on the host. This includes the following procedures:

1.Verifying the device files and drivers (see page 36)

2.Creating the device files (see page 38)

3.Creating the physical volumes (see page 41)

4.Creating new volume groups (see page 42)

5.Creating logical volumes (see page 45)

6.Creating the file systems (see page 47)

7.Setting the I/O timeout parameter (see page 49)

8.Creating the mount directories (see page 50)

9.Mounting and verifying the file systems (see page 51)

10.Setting and verifying the auto-mount parameters (see page 52)

The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-xdevices on the disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For further information on LVM configuration, see the HP-UX user documentation.

HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure SCSI disk devices. See appendix C (page 73) for further information.
