Folks,
did anyone notice a problem with HP LTO3 drives in SSO configuration,
running NBU 5.1 on Solaris 8 ?
Once - twice a week I have bptm debug logs reporting in the middle
22:03:41.746 [19156] <2> send_brm_msg: MEDIA NOT READY

and immediatly after in /var/adm/messages I see

Drives "lock" up and becomes iresponsive.
Front panel light show no signs of problem with solid green light on.
Pressing eject button does not do anything.
Brocade 4100 switch port does not "see" the drive anymore and shows
"In_Sync" instead of the "Online".
The only way to bring the drive back is the powercycle.
A minute or two after the powercycling I can eject the tape and see
fctl: [ID 517869 kern.warning] WARNING: 3799=>fp(1)::N_x Port with
D_ID=150500, PWWN=500104f0005ddda2 reappeared in fabric
in /var/adm/messages
Drives and library are at the latest f/w revision.
SUN and STK are clueless, but still looking for the last week.
