We have this problem and have tried all recent versions of the JNI driver.
We've been working on this for months and have found the problem to be
related to the rdac driver (we have A3500's). You can comment out all
rdnexus.conf entries that you don't need and see if you get sg devices built
as expected. This worked for us on one server, but not on another.
If this doesn't work you may be SOL. We have this issue open with STK, Sun
and Veritas. So far the only thing they've suggested is to try QLogic cards
(didn't help). sg has a problem, but no one nows what it is.

Subject: [Veritas-bu] Veritas Netbackup sg problem
The latest certified HBA code is 2.5.9, available from JNI or EMC. I'd move
up rather than down to 2.3 but I'd steer clear of the EZFibre utility for
now. The version of EZFibre that comes with 2.5.9 doesn't work, the 2.1
version is current but it isn't 100% either.
We're also having a lot of trouble getting the Solaris/JNI/Veritas/
Brocade/EMC/STK vendor stack to work correctly, but not
the same problems you are having.
Cheers,
gb

Subject: [Veritas-bu] Veritas Netbackup sg problem
hi all,
I am currently using a STK L180 with JNI's fibre channel card on
Solaris
2.6.
We planned for a Share Storage Option for Netbackup and have already
implemented
the Master Server. It works well.
On implementation of the Slave server which uses the same set of tape
drivers
with the master server with the same hardware configuration, problems
happened
on
/dev/sg attachment of the Fibre Channel tape drives when the driver is
loaded:
sg56 attach: - soft state zalloc failed
sg57 attach: - soft state zalloc failed
sg58 attach: - soft state zalloc failed
sg59 attach: - soft state zalloc failed
sg60 attach: - soft state zalloc failed
sg61 attach: - soft state zalloc failed
and the sg driver of the fibre channel tapes drivers are NOT attached
and therefore Netbackup cannot function properly.
The scsi tape driver /dev/st, however, is attached and functioned properly.
The main differences between the master and the slave servers is that:
1) The slave server is currently using Networker, with the lus driver
loaded.
We will
decommission it after the Netbackup is functional.
2) The slave server is also attached to a Sun A1000, in which both lus and
sg
created huge amount of devices to it.
3) The slave servers is also attached to another small DLT library with 2
SCSI
DLTs
These two drives, however, function without any problem, with the sg
drivers
attached normally.
When we ask Veritas, they blamed the problem on the firmware of JNI card
(2.4.1)
and
request us to downgrade it to 2.3. We only read from the documents that it
is
related to
Sun E10K. We also consulted EMC and EMC, however, mentioned they do not have
any
experience with that firmware level at all.
We have another to-be slave sever which has more or less the same
configuration
with the
previous slave server. When we implement netbackup slave to that the problem
is
repeated.
Since the slave servers are very important to our production environment, we
cannot afford
any change to it unless we have a certain amount of certaintythat it would
fix
the problem.
I wondered if anyone has encountered such problems before and can share with
us?
thx in advance,
Michael Choi
