Re: [Veritas-bu] sgscan cannot see robot after library power cycle

Have you run a devfsadm? Also, what Solaris kernal are you running? There was 
an issue with a patch that basically destroyed the sg driver.

Subject: [Veritas-bu] sgscan cannot see robot after library power cycle

T1000 S10U4 master

There was a power outage on the library and now sgscan cannot see the robot.
/dev/sg/c0t5l0: Processor: "SUN     StorEdge 3120  D"
/dev/sg/c0t8l0: Disk (/dev/rdsk/c1t8d0): "SEAGATE ST330000LSUN300G"
/dev/sg/c0t9l0: Disk (/dev/rdsk/c1t9d0): "SEAGATE ST330000LSUN300G"
/dev/sg/c1t1l0: Tape (/dev/rmt/0): "HP      Ultrium 3-SCSI"
/dev/sg/c2t0l0: Disk (/dev/rdsk/c0t0d0): "ATA     HITACHI HDS7280S"

I'm thinking of running
/usr/sbin/modinfo | grep sg
126 7bb72da8   1718  97   1  sysmsg (System message redirection (fan)
188  13d4320   35d0 285   1  sg (SCSA Generic Revision: 3.6)
232 7b7cc000   2168  49   1  msgsys (System V message facility)
232 7b7cc000   2168  49   1  msgsys (32-bit System V message facilit)
/usr/sbin/modunload -i 188
/usr/sbin/modload sg


The machine in question also servers up NFS home directories. I don't want 
those to drop.

Do you think that will bring the robot back? Are there side effects to doing 
this?
