Autoloader Changer/Library on LUN 1+ "can't" be added to NetVault in Solaris, but "can" add drive (4044147)

Date: 03/2007
Affected NV Version: 7.4.5
OS Version: Solaris 8, 9, 10
Plugin version: N/A
Application version: N/A

Description:
Solaris does not scan for devices on any LUN other than 0 by default, but your autoloader uses LUN 0 for the drive and LUN 1 for the changer.

Symptoms:
Drives visible when trying to add the library to NetVault, but the changer is not.

1. edit /kernel/drv/sgen.conf. In side you should find some lines that look like what is below.

name="sgen" class="scsi" target=0 lun=0;
name="sgen" class="scsi" target=1 lun=0;
name="sgen" class="scsi" target=2 lun=0;
name="sgen" class="scsi" target=3 lun=0;
name="sgen" class="scsi" target=4 lun=0;
name="sgen" class="scsi" target=5 lun=0;
name="sgen" class="scsi" target=6 lun=0;
name="sgen" class="scsi" target=7 lun=0;
name="sgen" class="scsi" target=8 lun=0;
name="sgen" class="scsi" target=9 lun=0;
name="sgen" class="scsi" target=10 lun=0;
name="sgen" class="scsi" target=11 lun=0;
name="sgen" class="scsi" target=12 lun=0;
name="sgen" class="scsi" target=13 lun=0;
name="sgen" class="scsi" target=14 lun=0;
name="sgen" class="scsi" target=15 lun=0;

2. Copy this section to just below the original section in the sgen.conf file, and edit the lun portion on the copy to read 1 in stead of 0, as seen below.

name="sgen" class="scsi" target=0 lun=1;
name="sgen" class="scsi" target=1 lun=1;
name="sgen" class="scsi" target=2 lun=1;
name="sgen" class="scsi" target=3 lun=1;
name="sgen" class="scsi" target=4 lun=1;
name="sgen" class="scsi" target=5 lun=1;
name="sgen" class="scsi" target=6 lun=1;
name="sgen" class="scsi" target=7 lun=1;
name="sgen" class="scsi" target=8 lun=1;
name="sgen" class="scsi" target=9 lun=1;
name="sgen" class="scsi" target=10 lun=1;
name="sgen" class="scsi" target=11 lun=1;
name="sgen" class="scsi" target=12 lun=1;
name="sgen" class="scsi" target=13 lun=1;
name="sgen" class="scsi" target=14 lun=1;
name="sgen" class="scsi" target=15 lun=1;

3. Run the command below

devfsadm -v -i sgen

4. Try adding the library to NetVault again.
