Configuring SG and ST Drivers

This procedure contains instructions for configuring the sg driver for SCSI targets 0 thru 6

and 8 thru 15 for fast or wide adapter cards.

In this procedure, you execute sg.build to add these targets to the st.conf, sg.conf

and sg.links files. Adjust the -mt and -ml parameters to create the range of targets and

LUNs required by your configuration. See the following command summary or the more

detailed explanation which follows.

▼ To configure drivers

1. Execute the sg.build script to add target IDs 0-6, 8-15, and LUNs 0-1 to the

following files:

/usr/openv/volmgr/bin/driver/st.conf

/usr/openv/volmgr/bin/driver/sg.conf

/usr/openv/volmgr/bin/driver/sg.links

cd /usr/openv/volmgr/bin/driver

/usr/openv/volmgr/bin/sg.build all -mt 15 -ml 1

The -mt 15 parameter specifies the maximum target ID that is in use on any SCSI

bus (or bound to a fibre channel device).

The -ml 1 parameter specifies the maximum target LUN that is in use on any SCSI

bus (or by a fibre channel device).

2. The file /usr/openv/volmgr/bin/driver/st.conf is used to replace the

following seven entries in the /kernel/drv/st.conf file:

name="st" class="scsi"

target=0 lun=0;

name="st" class="scsi"

target=1 lun=0;

name="st" class="scsi"

target=2 lun=0;

name="st" class="scsi"

target=3 lun=0;

name="st" class="scsi"

target=4 lun=0;

name="st" class="scsi"

target=5 lun=0;

name="st" class="scsi"

target=6 lun=0;
