Re: Cabling question

Actually, that 2780 is more than capable of handling the other 6 disks
(unless you want another LPAR). IIRC it has 3 SCSI ports, so you just plug
the SCSI cable that should be dangling around the 0595 into the second port
off the 2780.
Running a cable between controllers is only done on the "protected cache"
card pairs, like the 5580 and the like.
Besides, a 571A is a very very very slow card, it has no cache and is more
of a "tape controller" card.
I'm taking a picture of one of my 0595's with both bays connected to the
same card and sending it offlist to you.

Best Regards,

controls the 6 disks in the left (from the front) of the 0595. I want to
add 6 more disks into the right bay. I've procured a 571A card and stuck
it into U0595.001.13230A8-CB1-C04.

I think I then have to run a 42R4053 cable from C01 to C04 as shown in one
of our other 0595's. Is this the right cable? Why do I think that? Well
I have another 0595 and that is what it uses. Granted I didn't confirm
the identity of the two cards it connects.


Yes, I realize this is only temporary as 0595's will not be supported in
the next release and these 6 disks, cable, and card I've just bought is
only temporary.
