MSL2024 Tape Library

[Volker Halle]

Louann,

please have a look at the various SYSMAN IO *_WWID commands related to FC tapes.

Try SYSMAN> IO LIST_WWID to find out, if any FC tape WWIDs on your SAN have not yet been configured by OpenVMS.

Let me try this again. We installed the new tape drive library. We then configured the libraries into the system by doing the following:
Mc Sysman
sysman> set e/c
sysman> io find_wwid
syman> io auto
sysman> exit
$ show dev mg/full
We noted that 2 devices were created. $2$mga0 and $2$mga1

A few day later the site had to shutdown the nodes. They did not have to power off anything. They then rebooted the nodes, and after the reboot they tried to schedule a tape backup and the tape drives were no longer available. The site then did the Show dev mg/full and the two device, $2$mga0 and $2$mga1 did not list. The site then went through the SYSMAN steps again and the devices were then made available.

They should not have to do the SYSMAN steps everytime they perform a system shutdown and reboot. So, what needs to be done to prevent this from happening?

[Volker Halle]

Louann,

it should work the way you're expecting it to work. But apparently, it hasn't.

Do the systems do a full auto-configure during startup (check SYCONFIG.COM) ? Any error messages during the last startup ?

If the problem happens again, try a SYSMAN IO AUTO first. Does it solve the problem ?

Volker.

[Louann Duchemin]

Attached is a copy of the file, sysconfig.com. it would appear that we are not using the file. what is your take on it?

[EdgarZamora_1]

There is nothing in your SYCONFIG.COM and that's fine.

Please do a SYSMAN IO LIST and make sure there are no WWIDs listed. If that is the case, I strongly feel that your tape drives will show up on your next reboot.

[Volker Halle]

Louann,

I asked you to look into SYCONFIG.COM as this would be a supported method to skip auto-configuration during startup and later manually include SYSMAN IO commands, which could exclude certain type of devices.

Your SYCONFIG.COM does not contain such commands.

Volker.

Here is the output from SYSMAN IO LIST:

SYSMAN> io list

[EdgarZamora_1]

Well that was unexpected and not good...

I have, however, come up with a brilliantly plausible explanation! You used SYSMAN commands set e/c... io find...io auto...

are your two systems clustered? what account (username) did you use when you did the sysman commands? Was that a privileged account? Did you enable privileges (sysman do set proc/priv=all) before doing the io find and io auto? Please also do a SYSMAN IO LIST on the other system and post the output. I hope this is your problem and not something else.

[Louann Duchemin]

These are clustered systems. The account used for the IO FIND and IO AUTO was SYSTEM and yes this is a priviledge account.

Keep in mind that we are connecting the MSL2024 to a Fibre Channel Switch.

Good morning,

Does anyone elase have some suggestion as to why the tape drives are nolonger reachable after a system reboot?
