Re: Unsupported devices on V5R4

'zactly! Arn't feature codes fun! Frankie is full of this stuff and runs fine. He really DOES have some FC 6718's though ('Franken-rule') and they work find too.

By the way this feature code frenzy isn't getting any better. The same disk units that go in FC #0595s (which of course is the same thing as a FC #5095 except for mounting) have different feature codes if you put them in an EXP24 drawer! And the RAID card that drives those drives in the EXP24 can have at least SIX different feature codes depending on if it's in a 520 CEC, a 5790 or neither of those and if it's driven by an IOP or not! Another example is the FC #5702/5705/5712/5715 card. Yes it's all the same card, it's all how you use it.

Technically while the Rackcfg or WRKDSKSTS reports them as 6718s...they are 4318's when placed in a 270, 8xx or 5xx. The difference is the mounting HW. 67xx Hw fits in 170s 720s etc, which do not support V5R4.

Like wise on the tape.. IBM calls it a 4586 when in a 270. Again the Rackcfg or WRKDEVD will show it as a 6386, but it's wrong...

So your HW is Supported

Subject: Unsupported devices on V5R4

I have a 270 currently on V5R3 that I'd like to bring up to V5R4.

According to IBM (its website) it has two unsupported device types:

- 6x 6718 17GB disks
- 1x 6386 50GB quarter inch tape drive

Despite this, some people on this list reportedly have V5R4 running successfully on type 6718 disks.

Would anybody have any good or bad experiences with the 6386 tape drive on V5R4? Care to share?

Thanks,
Moe
