After installing all recommended patches, and upgrading the firmware on the V120 server, the culprit was a bad sd.conf file. This problem would have been solved a lot sooner had the workaround in bugID# 4895444 been correctly stated. Because of my problem and the recommendation of a Sun engineer, the workaround in the bugID has since been corrected. The workaround now correctly states that you can't have more than 8 LUNs per target. This problem is currently applicable to the L25 tape drive. Here is the recommended workaround copied from the bugID ( I only included the fix here) :
Change the scsi target id of the L25 controller where we do not have any
targets that have more than 8 luns. In this case we need to delete target 0 Lun
8,9,10 and 11. See Below for the changes that need to be made for the sd.conf
file from the one above. In this example we have only 8 luns per target, 0-7.

ORIGINAL POSTING:
Have recently purchased an L25 tape drive system, hooking it up to a V120, using a PCI SCSI-3 dual channel I/O card. The problem occurs when trying to reboot the V120. The L25 causes the V120 to hang during the boot process. Sunsolve reported a similar problem and suggested checking the sd.conf. I have checked the sd.conf file, and have had another admin check it as well, and we both agree the sd.conf file is correct. At the ok> prompt, probe-scsi-all reports correctly the library(robot) and the drive SCSI IDs that are set for the L25. The V120 is so badly hung that it fails to recognize a "stop-A", thus requiring a power cycle for a reboot. I have also loaded the recommended patch as suggested from the Sun system handbook for the L25, but this provided no success.
