Re: dat72 autoloader

I've tried that, but unable to coax the drive to go online.

The only way I can put the drive online is by pressing various buttons on the front panel of the unit.

Kinda makes the "autoloader" part of this unit pretty useless.

I'm thinking there must be a dip switch setting that needs to be changed.

No experience of that make/model, but -

We have a HP dat 40x6 autoloader (8 tape magazine), and its configured like this in sysgen:-
LDEV: 777 DEVNAME: OUTDEV: 0 MODE: R
ID: DDSAUTO RSIZE: 128 DEVTYPE: TAPE
PATH: 0/0/1/0.5.0 MPETYPE: 24 MPESUBTYPE: 7
CLASS: TAPE

AND we do this in sysstart:-

devctrl 777,enable,enable

The parms available are compress, eject, and load - we have not specified load in the above - check help devctrl for options.
It always loads next tape on end of a backup, EVEN though SHOWDEV does not show a tape at ready - maybe because we are not setting Load to online? Its showing two leds (ready) now after last nights backup , but showdev gives AVAIL.

If a tape gives an error I think it moves on to the next one. In this mode (eject=enable), I cant get my programmatic bring on line to work.

We also have a dds 3 single drive on the traditional ldev 7. We set this to Eject= disable, as this allows for doing a store, and programmatically putting the tape back on line remotely - avoids having to be on site to do backup & restore.

Subject: [HP3000-L] dat72 autoloader

I have a Certance DAT72 autoloader, model no. CDL 432 configured on
an HP3000 and have no problems reading from and writing to the unit.

What I am having difficulty with is trying to automatically load the
next tape from the 6-slot magazine.

Trying the DEVCTRL.MPEXL.TELESUP command with varying parameter
values has not been fruitful. (Specifically, DEVCTRL.MPEXL.TELESUP 8
EJECT=ENABLE LOAD=ONLINE)

Also, looking at the dip switches available do not appear to offer
any obvious solutions there (I don't see a switch associated with the
stacker or random mode operation).

Does anyone have any experience with this model of autoloader or any
suggestions as to how I can configure it so I can issue a command to
load the next tape in the magazine ?

Thanks.
