Hello.

I'm using NetBackup 3.2 on an E250 Master and an E450 media server.
We replaced a a bad SCSI cable and recabled so that there are two drives per 
adapter.  The robot and two drives were on the same adapter, and we placed 
the tow drives on there own adapter.

The drives are noticed with sgscan, but I didn't change anything in the 
config since the drives were still associated with the same /dev/rmt/#.  
Should I have removed them and readded them anyway?

Media server:
/dev/sg/c3t4l0: Tape (/dev/rmt/0): "QUANTUM DLT7000"
/dev/sg/c3t5l0: Tape (/dev/rmt/1): "QUANTUM DLT7000"
/dev/sg/c5t2l0: Tape (/dev/rmt/2): "QUANTUM DLT7000"
/dev/sg/c5t3l0: Tape (/dev/rmt/3): "QUANTUM DLT7000"
/dev/sg/c6t4l0: Tape (/dev/rmt/4): "QUANTUM DLT7000" -added drive to config
/dev/sg/c6t5l0: Tape (/dev/rmt/5): "QUANTUM DLT7000" -added drive to config


Master: new

/dev/sg/c2t2l0: Tape (/dev/rmt/0): "QUANTUM DLT7000"
/dev/sg/c2t3l0: Tape (/dev/rmt/1): "QUANTUM DLT7000"
/dev/sg/c5t0l0: Changer: "ATL     P3000    6310070"


The following are the errors thar are seen when a backup is attempted.

The backups failed with error 54.

The bprd logs on the MediaServer show

17:30:11 [2212] <2> hosts_equal: name1=MediaServer  name2=MasterServer

Nothing was changed in the bp.confs or /etc/hosts.

I'm sending this out in case someone else has an idea of where I should look 
next.

Thanks.
