RE: Unattended backup

John,

Years back, we had a 3590 E11 with auto cartridge loader, but from what I remember, it could only be used as tape device, TAP01

Subject: Unattended backup

Still riding system to oblivion. We >may< be losing our only opportunity for an attended backup every other week. I have been asked to explore alternatives.

No money.

I read in Infocenter that GO SAVE 21 has a capability to be set up to 24 hours in the future. Not a scheduled job, just sits in DLYJOB. The thought occurred to me of writing a CL that would be submitted to controlling subsystem (BCTL in our case) which would end to restricted state and perform backup. Just a little afraid of that. If something failed, with no workstation available, how could anybody know?

I retrieved the source for the GO SAVE 21 CLP, QMNSAVE. Two parms are passed, &DFT and &CANCEL DFT has a length of 118, but the defaults data area has a length of 200. I am assuming that is just a quirk, as the data area is blank beyond 120 or so.

It looks like the CaNCEL parm is populated and sent back.

I am thinking that this retrieved source could be modified to have no parameters. Just do RTVDTAARA and run the commands. Add an appropriate DLYJOB at the top so it could be started from the console and it would wait until the appropriate time. Would need to also end the online system before subsystems are ended. I have that code already.

Final piece is to get the media library to pull tapes as needed. I presume the changes to accomplish that are made through the front panel? This is
3590 E11.

Gets a bit more confusing: We have a single 3590. yet a WRKCFGSTS *DEV
TAP* shows:

TAPMLB01 VARIED ON
TAPMLB02 VARIED OFF
TAP35 VARIED ON
TAP35OLD VARIED OFF

TAPMLB01 was created by auto config. It shows device type 3590 E11. This shows resource of TAP01 deallocated.

TAPMLB02 has *RSRCNAME for device type and model. No resources listed.

Can't vary on TAPMLB02 after vary off of TAP35. I am not surprised, based on no resoueces.

I do not know why there are two MLBs. My thought is both are "incorrect".
Many years ago, there was a TAP01.

Ran WRKHDWRSC TYPE(*STG), TAPMLB01 is only tape library.

Was media library even set up correctly? It has never been used, as far as I know.

I can add config source if it will make any sense.
