Configuring HP-UX File System
The HP-UX Operating System has now been modified to communicate with the
RAID Array Controller.
Enable Volume Set Addressing for HP Host Mode
HP systems require volume set addressing in order to present more than eight
LUNs to the host. The new host port mode is HP_VSA.
In order to use the RAID Array from the HP system, perform the following steps:
1. Create new virtual disks on your RAID Array and assign LUN IDs to each
virtual disk created.
Note: If not yet created, you can use the Client (refer to the HP StorageWorks
Command Console V2.5 User Guide
). LUNs created on the Array must be assigned
consecutively starting with LUN 0. Currently there is an HP-UX limit of eight LUNs per
TARGET, so plan accordingly. A new host operating mode (HP_VSA_ is now available
which permits the assignment of 128 LUNs per HBA/Array.
Refer to the HP System Administration Tasks Manual for instructions on the
following tasks:
— Adding the RAID storageset to a volume group.
Note: Do not use the System Administration Manager (SAM) to Create/Extend Volume
Groups. Creating/Extending Volume Groups must be done using HP-UX commands.
When SAM scans for hardware, any HSG80 controller LUNs created after the first LUN
are not parsed correctly by SAM and consequently, cannot be selected to create a
volume group. The solution around this problem is to use HP-UX commands to
create/extend the volume groups and then use SAM to create and manage logical
volumes.
— Determining the mount point directory on your system.
— Using the mount command to mount the device on your system.
— Editing the
etc/fstab file if you want this device mounted each time
you boot the system.
