Configuring host device drivers for a PRIMEPOWER host

Complete this task be to update the PRIMEPOWER driver configuration file. This procedure gives you access to target and LUN pairs that are configured on the storage unit.

1. Change to the directory by typing: cd /kernel/drv
2. Backup the sd.conf file in this subdirectory.
3. Edit the sd.conf file to add support for the target and LUN pairs that are configured on the host system.
   Note: Do not add duplicate target and LUN pairs.

   Figure 1 shows the lines that you must add to the file to access LUNs 0 - 49 on target 0 for fibre-channel.

   Figure 1. Example of sd.conf file entries for fibre-channel

   name="sd" class="scsi"
           target=0 lun=0;
   name="sd" class="scsi"
           target=0 lun=1;
   name="sd" class="scsi"
           target=0 lun=2;
   name="sd" class="scsi"
           target=0 lun=3;
   name="sd" class="scsi"
           target=0 lun=4;
   name="sd" class="scsi"
           target=0 lun=5;
   name="sd" class="scsi"
           target=0 lun=6;
   name="sd" class="scsi"
           target=0 lun=7;
   name="sd" class="scsi"
           target=0 lun=8;
   name="sd" class="scsi"
           target=0 lun=9;
   name="sd" class="scsi"
           target=0 lun=10;
   .
   .
   .
   name="sd" class="scsi"
           target=0 lun=48;
   name="sd" class="scsi"
           target=0 lun=49;

   Figure 2 shows the start lpfc auto-generated configuration.

   Note: You will delete anything that you put within this auto-generated section if you issue the pkgrm command to remove the lpfc driver package. You might want to add additional lines to probe for additional LUNs or targets. Delete any lines that represent lpfc targets or LUNs that are not used.
   Figure 2. Example of a start lpfc auto-generated configuration

   name="sd" parent="lpfc" target=0 lun=0;
   name="sd" parent="lpfc" target=1 lun=0;
   name="sd" parent="lpfc" target=2 lun=0;
   name="sd" parent="lpfc" target=3 lun=0;
   name="sd" parent="lpfc" target=4 lun=0;
   name="sd" parent="lpfc" target=5 lun=0;
   name="sd" parent="lpfc" target=6 lun=0;
   name="sd" parent="lpfc" target=7 lun=0;
   name="sd" parent="lpfc" target=8 lun=0;
   name="sd" parent="lpfc" target=9 lun=0;
   name="sd" parent="lpfc" target=10 lun=0;

   name="sd" parent="lpfc" target=16 lun=0;
   name="sd" parent="lpfc" target=17 lun=0;
   name="sd" parent="lpfc" target=17 lun=1;
   name="sd" parent="lpfc" target=17 lun=2;
   name="sd" parent="lpfc" target=17 lun=3;

4. Type either:
   1. reboot -- -r from the Open Windows^® window to shutdown and restart the PRIMEPOWER host system with the kernel reconfiguration option
   2. boot -r from the OK prompt after you shutdown

   The fibre-channel adapters that are supported for attaching the storage unit to a PRIMEPOWER host are capable of full-fabric support. Ensure that all fibre-channel driver configurations include worldwide port name, worldwide node name, port ID, or host adapter binding of target LUN pairs.

   Binding of target LUN pairs implements the PRIMEPOWER fibre-channel host adapter configuration file that is installed by the adapter software package. Refer to the manufacturer's adapter documentation and utilities for detailed configuration instructions.

   You can tune fibre-channel host adapter configuration files for host system reliability and performance.
