Re: Connecting a 3581 tape loader to 2749 card on 520

Very old thread, but...

Thanks for the advise. I finally talked the boss into moving the cards, and
referenced this tread to show him where it needed to go. The 2488 was
controlling a Twinax brick that was not being used. Now I have to figure
out how to use the tape drive. I will find the manual for the 3581-H17 tape
drive - only an Ultrium 1, but better than nothing.

Thanks again for your help!!

Jim,

1 - we need to know what card slots and in what unit. This is important
to tie it into a bus. If the slot holding the 2749 is not on the same bus
as the 2844 then a no go.
2 - I recommend that, if you have the slots available, you put a new 2844
and the 2749 card on a different bus. Backing up to a tape drive on the
same bus as your disk drives will be abysmal performance.

Rob,

Thanks for the reply.

The machine is HMC controlled.

I would do concurrent maintenance, but as far a I can tell, this 2844
controls the load source disks (and _all_ the disks) as well. SST
won't let me power it down. It shows up in iNav All Hardware view as
Resource;

Cmb01 - Type-Model 2844-001 S/n 062
Lin03 Comm Adapter
Ctl01 Workstation Controller (this can and will go away when we change
over)
Dc01 Storage Controller
Dd002 Disk Unit
Dd001 Disk Unit
Dd003 Disk Unit
Opt01 Optical Storage Unit
Tap01 Tape Unit (internal - not the one I am trying to add)
D01 Device Services
Dd004 Disk Unit

In talking with the boss, this card/cable/Drive combo was working on
an 820 before it was upgraded to a 525. He was told that the 520 that
is now powering portions of the web (and will do all web serving as
soon as I get it up to V5R4) would be able to utilize this drive. I
believe that it is a matter of configuring the cards correctly to get
this accomplished.

What we don't know is if they are in the same bus. For example if you

put

the 2844 in slot 3 and the 573E in slot 4 and the 2749 in slot 5 and

slot

5 happens to be on the next bus it won't know about the 2844.
What's a 573E?
What slots on what unit are these cards in?
Is this machine HMC controlled?
And you actually power off the machine to remove and add cards? I do

that

live, via concurrent maintenance in STRSST.
