Configuration of the new devices requires superuser/root access to the HP-UX host system and should be performed by the HP-UX system administrator. If you have questions or concerns, please contact your Hitachi Vantara representative.
Device recognition
The devices should be installed and formatted with the ports configured before the host system is powered on. Type the cfgmgr command to force the system to check the buses for new devices.Device files and driver recognition
The device files for all new devices (SCSI disk and raw/FX) should be created automatically during system startup. Each device should have a block-type device file in the /dev/dsk directory and a character-type device file in the /dev/rdsk directory. The SCSI disk devices must have both device files. Raw/FX devices only require the character-type device file.
If the device files were not created automatically when the HP-UX system was restarted, issue the insf -ecommand in the /dev directory to instruct the HP-UX system to create the device files. After executing this command, re-verify new device recognition.
File systems
The default file system type for HP-UX version 11i is vxfs.
Device parameters
When device files are created, the HP-UX system sets the IO time-out parameter to its default value of 20 seconds and the queue depth parameter to its default value of either 2 or 8. You must change these values for all new disk devices on the storage system.
The IO time-out parameter for the disk devices on the storage system must be set to 60 seconds.
Queue depth parameter
The HP-UX system automatically sets the queue depth to a default value e of 2 or 8, depending on the installed HPE options and drivers. You must change the queue depth values for all new disk devices on the storage system. You can adjust the queue depth as needed to optimize the I/O performance of the devices. For details, see Host queue depth.
Using the scsictl command, you can view and change the queue depth parameter for each device one volume at a time. However, the queue depth is reset to the default value the next time the system restarts. Therefore, you must create and register a start-up script to set the queue depth for the disk devices each time the system restarts.
Mount directories
Choose a unique name for each mount directory that identifies the logical volume.
File system verification
Mount the file system for each new logical volume and verify the file systems.
