Re: Entire RAID set non-reporting -- MIDRANGE-L

Well, I don't have my manual here to check, but one possibility is the system password needs to be entered.
Try a manual IPL and see if you are prompted for it.

A few other things to check. (Did you recently apply PTF's ?).
First - see if you can IPL from the 'A' side ('A N').
As you're on V4R3, see if you have PTF MF22244. If you do, make sure you also have MF21962 (MF24930 is latest superseding PTF).
Also suggest applying MF22745 & MF24730.

PTF MF20951 can cause SRCA6005090. Make sure you have MF21590 (or newest supersed MF24979) installed.

If it is a hardware problem, does one of the reference codes show a serial # for one of your disks (maybe in 17-3) ?

Subject: Entire RAID set non-reporting

I was gone from my office for 9 days doing a CISC to RISC migration which went beautifully -- jobs that used to take hours now literally take minutes. It's great. Plus now I get to code to V4R5 features instead of V3R2, and get to take advantage of all that great stuff Hans and Company have been adding to RPG. But returning to my home office, my personal 40S does not want to IPL normally. I typically leave it running 24/7, but turned it off since I was going to be gone so long. It was last shut off in October, when I was gone for over 2 weeks. My 40S-2109 has ten 6606 drives -- two mirrored on the MFIOP for the load source, and eight in a RAID set attached to a 6502 controller in a 7117 expansion chassis. All are in ASP 1. It is running V4R3, although I had been planning to install V4R5 today. Guess that will have to wait for now... An IPL set to B N results in the attention light with the following SRC's: 11-3 A600 5090 12-3 09B0 0160 13-3 0020 0000 14-3 0000 0150 15-3 0300 FFFF 16-3 6606 5074 17-3 0000 A0C6 18-3 0008 0000 My V4 Service Functions manual (SY44-5902) gives me most, but not all, of the explanation of these codes. In particular, it does not tell me what the 5090 unit reference code means in the A600 xxxx LIC interruption SRC. Nor does it tell me what "cause code" 0020 means in function 13-3. Function 14-3 flags 0150 point to my 6502 card and the eight 6606 drives on it. I am less sure of function 15-3's unit address of 0300. If that is the drive DST reports at I/O bus 0, controller 3, device 0 then it would be storage unit location 12 and the third of the eight drives non-reporting. The serial number A0C6 in function 17-3 doesn't seem to match anything or at least not in the 6502 controller and the 6606 drives. A manual IPL stops at IPL step C600 4008 (during sys config testing) and puts up a display on the console reporting some disks as missing. Displaying the detail shows all 8 drives in the expansion unit as missing. I wouldn't suspect 8 drives to exhibit the infamous 6606 "stiction" problem at the exact same time, and not the other two attached to the MFIOP. So my inclination is to suspect the 6502 controller or the expansion feature power supply. But I'm measuring 12.24 and 5.04 vots on the power leads, and DST shows the status of the 6502 as "Operational". With the covers off so I can listen closer, I can hear when the first two drives on the MFIOP are powered up sequentially. But then I don't even hear it trying to start the other 8 drives in turn. Also, tapping lightly on the drives during this time when I'd expect them to spin up seems to not have on effect either. I don't have a spare 65x2 controller laying around to try swapping it out even though it reports as operational under DST. How do I narrow this down more? TIA, Doug
