[Veritas-bu] Status 84's
2001-06-18 23:30:57
We just had a 9840 replaced today, so we'll know tomorrow how that is doing.
Thanks for the info. I'll probably get STK out here to do testing on all
there drives.

Hi Terry,
We were receiving a huge amount ( > 4 / day). We had datalink run extensive
diags on our tape drives (DLT 7k), and it turned out there
was an issue with 3 of them. Since they have been replaced (2 weeks ago),
there has not been 1 status 84.

Question regarding status 84, is there anyone out there that has
experienced
a high volume of 84's on .
Here is the tape SAN configuration:
HP-UX 11.00
NBU 3.2, Patch J0820443
STK L700
9840 Fiber Drives with 1.28.122 microcode
Brocade/STK Silkworm 2800 with Fabric O/S 2.1.5a
NBU SSO 3.2
HBA HP PCI Tachyon TL A5158A rel B.11.00.03
Here is the situation. We are receiving numerous status 84's on backups
which involve the tape SAN. Now, I know there isn't a problem with the
tapes or drives. Some of the backups are receiving the 84 without
backing
up any data. This error also occurs when a tape has ended and a new one
is
mounted in the middle of a backup.
Question: When NBU needs a new tape to continue a backup, where is the
data
that is being sent buffered at?
Our data buffers on the servers are at the default of 32k and the switch
has
a 2 meg buffer for each port. Is this enough buffering to swap out a
tape
and bring in a new one.
Thank you,
Terry
