Does anyone else still use L&TT for their MSLs?



I've got a 2 node VMS cluster (v8.3 - Alpha ES47's). They're in two separate locations 6 miles apart. Correspondingly, I have 2 MSL 5026SLs (one in each location), but I get 2 different responses when I use L&TT (v4.2) for the same command. Needless to say, it gives more differences as you continue further on in the menu.

Would anyone have an idea as to what I might have set up differently to generate such a type of thing?

I've asked HP Support in the past, but they seem to only have folks that do Windows these days ("they're basically the same" - yeh, but they're *not* the same - they're on 2 different O/S' with 2 different interfaces)

Thoughts welcome,
Rich

Re: Does anyone else still use L&TT for their MSLs?

The missing $2$GGA1: could be due to

- different mapping on the NSR
(I guess the libraries have an internal E1200 board)

and/or

- differences in SYS$COMMON:[SYSEXE]SYS$DEVICES.DAT
-- you have 2 system disks and/or
-- a file in SYS$SPECIFIC:[SYSEXE]


This different order of devices can be a result of the SAN topology (on which switch/port a storage device or a server is connected).


A tape drive should not come up in the 'Libraries/Autoloaders:' section, but I would first verify / cleanup SYS$DEVICES.DAT and do a cluster reboot to clean up stale data (yes, I understand that ruins your uptime ;-)

Uwe,

Thank you for your response. A place to start is what I was looking for. I'll be taking a look at my fabric and the NSRs'(I have 2). If necessary, I'll get HP Network Support to help me (I hope); we've got a contract, so it's (theoretically) possible :^)

Your response specifing that the drives *shouldn't* show up in the Library section let's me know which one is set up correctly. I wasn't sure before.

Thanks for your thoughts,

Hi Rich,

Based on the screenshots, I don't think there is a problem with the NSR mapping (if both the nodes are able to see the libraries properly in show device output). Till LTT v 4.4), we had a problem in LTT wherein it couldn't map the drives of a FC connected library properly.

The issue has been fixed from LTT v 4.5 onwards. Installing LTT v 4.7 should resolve the anomaly.
