We're running 6.5.5, and use a similar command from within a script, and it
works fine. Here's whats in our script:
$VMCHANGE -vh $volumeHost -res -m $tape -mt $thisMT -rn $robotNumber -rh

Looks like the big difference is that we specify the -rn and -rh. I've
I believe it tracks the drives by serial number. When you reboot you’ll notice
that the device paths get automatically updated.

I assume you're doing this to help keep the devices from becoming
mis-configured in NBU after a reboot - because the lack of persistent binding
ends up changing the target number for the drives. We've always used
ENABLE_AUTO_PATH_CORRECTION in the vm.conf file for this, which seems to work
We've got NBU 6.5.3 and VCB 1.5 running, and multiplexing works well for us.
You mention the storage unit is set to a max MPX of 2 - something to check if
you haven't already, is to make sure that the schedules are also set to 2.

Devon,
In 6.5.1+, you can use and define a storage unit group as the source - then
within the Duplication Tab, selecting Advanced configuration, you'll need to
define each
You can't use storage unit groups as the source, and I don't think Vault will
let you use a storage unit group as a duplication destination - you wouldn't
want that anyway since the duplications would probably end up going over the
network.
You'll want to setup the vault profile to choose all

We don't do anything special for recovery of our SAN media servers (or
any media servers) during a DR test. We build new media servers, and
then use FORCE_RESTORE_MEDIA_SERVER entries in our Master server's
bp.conf file, which forces the restores to be done by the new dr
servers. Ex:

Chris,
To me it looks like there's a 1Gb bottleneck somewhere (90MB/s is about
all we ever got out of 1Gb fibre back in the day). Are there any ISL's
between your tape drive, your switch, and your server's HBA? Also, have
you verified that your tape drives have negotiated onto the fabric as
2Gb
66MB/s.

Not sure if anyone else has responded yet, but you can tune the number
