I am currently using a STK L180 with JNI's fibre channel card on Solaris
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
with the master server with the same hardware configuration, problems happened
/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.
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
These two drives, however, function without any problem, with the sg
When we ask Veritas, they blamed the problem on the firmware of JNI card (2.4.1)
request us to downgrade it to 2.3. We only read from the documents that it is
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
previous slave server. When we implement netbackup slave to that the problem is
Since the slave servers are very important to our production environment, we
any change to it unless we have a certain amount of certaintythat it would fix
I wondered if anyone has encountered such problems before and can share with us?
