Hello group,
=20
I'm running NB 5.0 on a Sun 480R - Solaris 9 with two 280R's as media
servers. My tape unit is an IBM with 12 LTO fiber attached tape drives.
Here's the problem:
=20
Daily my servers (both the master and the two media servers) will lose
visibility to some of the tape drives. I know this by running cfgadm
-al and it shows something like the following:
=20
c3 fc-fabric connected configured unknown
c3::500507630f404301 tape connected configured unknown
c3::500507630f404302 tape connected configured unknown
c3::500507630f404303 tape connected configured unusable
c3::500507630f404304 tape connected configured unusable

c3::500507630f404306 tape connected configured unknown
c3::50060482cafd8e8c disk connected configured unknown
c4 fc-fabric connected configured unknown
c4::500507630f404307 tape connected configured unknown
c4::500507630f404308 tape connected configured unknown
c4::500507630f404309 tape connected configured unknown
c4::500507630f40430a tape connected configured unknown
c4::500507630f40430b tape connected configured unknown
c4::500507630f40430c tape connected configured unknown
c4::50060482cafd8e83 disk connected configured unknown
Notice the two drives that show "unusable". Now to fix this I've been
running the following command.
cfgadm -c configure c3
In my message log I notice reference to

Does this problem have to do with a NetBackup timeout value or is this a
SUN issue? I've got SUN support on these systems and will work the
issue with them if needed, but I didn't know if someone else on this
group might have run into the same issue. Maybe there is a kernel
setting that needs tweaking?
Thanks for any help in advance.
Scott
