24 Implementing an Open IBM SAN
4. Either you or an IBM SSR configures the host system for the ESS by using
the instructions in your host system publications.
1.7.2 Installing the 2105 host install script file
This section provides the instructions to install the 2105 host install script file
from a compact disc for the ESS on your host system.
Before installing the 2105 host install script file, connect the host system to the
ESS. See Attaching an ESS to an open-systems host with SCSI adapters.
Install the 2105 host install script from a compact disc. You must have superuser
authority to complete these instructions. The following must be taken into
account:
1. You can only install and run the IBM 2105 set queue depth program (version
2.7.1.00) on HP-UX operating system 10.01or later.
2. If an ESS was used with the SAN Data Gateway on a Hewlett Packard host
system and the LUNs were created as Fibre Channel devices by spoofing
HP-UX and describing the ESS device types as Sun or other non-Hewlett
Packard Fibre Channel device types, the LUNs created under this false ID
must be deleted and recreated as Hewlett Packard device types.
Perform the following steps to install the 2105 host install script from a compact
disc.
1. If you do not already have a directory called /SD_CDROM, type mkdir
/SD_CDROM to create a new directory.
2. Insert the compact disc into the CD-ROM drive.
3. Mount the drive as a file system.
4. Type: ioscan -fnkC disk
Look for the device name on the list with a name of either compact disc or
DVD.
Type: mount -o cdcase /dev/dsk/c_t_d_ / SD_CDROM
Replace /dev/dsk/c_t_d_ with the device special file found in step 4.
5. Type: swinstall -s /SD_CDROM/hp-common/IBMis.depot
Note: The IBM Subsystem Device Driver 1.1.3 supports the Hewlett Packard
host system in a clustering environment. To have failover protection on an
open system, the IBM Subsystem Device Driver requires a minimum of two
Fibre Channel adapters. The maximum number of Fibre Channel adapters
supported is 16 for a total of 16 Fibre Channel ports.
