Hello.

Time to revive an old problem that I have.

I updated SunFire V240 system from Solaris 9 to Solaris 10 U4. I'm 
using NetBackup 5.1 MP4 on this system. After I updated this machine,
using Live Upgrade (lu) if that matters, I get the following messages
shown on the console:

Because of this, NetBackup does not work.

When I go to the ok-prompt of the system, I get:

{1} ok probe-scsi-all
/pci@1c,600000/scsi@2,1

  Unit 0   Removable Tape     HP      Ultrium 2-SCSI  F67A

/pci@1e,600000/scsi@2

When I boot the system, /dev/rmt/0cbn is:

bash-3.00# ls -la /dev/rmt/0cbn
lrwxrwxrwx   1 root     other         47 Aug 29  2005 /dev/rmt/0cbn -> 
../../devices/pci@1e,600000/scsi@2,1/st@5,0:cbn

When I re-activate the S9 boot environment, there are no timeout 
messages reg. this device (or any device at all).  Ie. NetBackup 
works fine again.

I searched sunsolve for
HP Ultrium 2, but only found references to an updated firmware in document
ID 116622-03. When I run "tload" from this firmware update tool, it
scans the system and displays the supported/attached devices:

bash-3.00# ./tload

ATTACHED DEVICES:

Device          Supplier  Product           Rev   Serial Number  Device State
--------------  --------  ----------------  ----  -------------  -------------
1:0ln           HP        Ultrium 2-SCSI    F67A  HUL5E02510     Available    

Doesn't that mean, that the system can communicate with the tape drive?
But why do I get "Connected command timeout" messages?

Thanks,

Alexander
