2193.0. "SLS - HSJ50 - TL810 failover "?"" by CSC32::D_DONOVAN (SummaNulla(The High Point of Nothing)) Fri Feb 07 1997 14:16

Configuration:

OpenVMS VAX V6.1 
SLS V2.8-2 (ECO2)
Dual-Redundant HSJ50s (V5.0)
TL810

Problem:

	Customer has been having problems with failover of his TL810 
	between a dual-redundant HSJ50 pair.  During backups last
	week a hard-failure occurred on the primary HSJ50; the four
	tapes went into mount verification; SLS reported the devices
	misconfigured; the backups failed with "medium is offline".

	Note: 	I'm getting this information "second-hand" so I'm hoping
		that I've been faithful to the sequence of events.

Discussion:

	The situation has since stabilized however, we would like to know
	if the HSJ50 has ever been tested with SLS in this configuration 
	or if there are any "known" issues that may be in play.

Thanks,

Dennis

You will have to provide more information before I can give you
any useful advise.  In particular, I need the details regarding "SLS 
reported the devices misconfigured".  What exactly were the error
message?   The dual-redundant hsj50 configuration is supported by
VMS and SLS.

Hi Dennis,

I have had many problems with TL822's and pairs of HSJ40's. I think your
customer has the messages the wrong way around. The HSJ can report the devices
are misconfigured, VMS would then have seen the devices go offline(and SLS).

My customer still seems to have problems with tape drives and or the pass device
changing controller. This change seems to happen even without errors, so the
only safe workaround for my customer is to set the devices with a preferred path
on the controllers.

Good luck,

Scott.
