Hello,
I have UNIX and Windows Media Servers sharing 20 DLT
7000 drives from our StorageTek L700 over a Brocade
fabric. On the Sun servers with JNI FCI-1063 HBAs I
can't seem to get persistent binding working properly.
Every time I reboot a server the drive numbers change
and I have to go through and reconfigure the paths in
Netbackup. Here is a sample of the st.conf I'm using:

tape-config-list=
        "QUANTUM DLT7000",      "Quantum DLT7000",
"DLT7k-data";
DLT7k-data =   
1,0x38,0,0x3D639,4,0x82,0x83,0x84,0x85,2;

# Cletus Bridge #0
name="st" class="scsi" target=10 lun=0 hba="fca-pci1"
        wwpn="100000e002021baa";
name="st" class="scsi" target=10 lun=1 hba="fca-pci1";

# Chalmers Bridge #1
name="st" class="scsi" target=11 lun=0 hba="fca-pci1"
        wwpn="100000e002021b9e";
name="st" class="scsi" target=11 lun=1 hba="fca-pci1";

[...]

There are two drives per SCSI/Fibre bridge and the
Windows/HP/AIX hosts always detect the drives in
correct order, but for whatever reason Solaris
doesn't. I'd like to be able to copy the
/usr/openv/volmgr/database/ltidevs file between the
hosts rather than doing each by hand using tpconfig or
the GUI.

Also, how would the sg driver configuration look on
Solaris using persistent binding --or does that even
more using ACSLS?

Finally, once the binding is proper can I dynamically
reconfigure them using drvconfig;devlinks;tapes?

Thanks in advance for any insight you can provide.
Joe
