[Fwd: RA90: What's error E0 and 7C (and others)?]

Hi, please, someone with an RA90 service manual (Joop?) can you give me a list of the error codes? Or is the RA9x service manual scanned somewhere? I have tested out my two SA600 racks' worth of RA90 drives and found that 7 out of 16 have some problem. They all had a problem with their fans not spinning up at first, but after a couple of attempts this seems like not a big problem. There is only one that's really dead (drive, not power supply) in that the green LED at the rear (on the power supply) lights up only dim and nothing will come up at the front at all. This is same with a different PSU swapped on, so it's the drive, not the PSU. Not quite sure what to do with that one. But 4 or so of them fail only when trying to spin them up and return an error code 7C. It sounds like they do spin up but when trying to seek the fist time they immediately determine they failed. OTOH, in at least one case just retrying it a couple of times will eventually bring it up and running. Another 2 of them fail earlier when trying to spin up. They come up with erorr E0 pretty much as soon as it's trying to spin up. Yet another one comes up with various errors even before spinning up, and one more seems to work but somewhere down the road may or may not fail with various errors. 54 is one I can remember, but there were all kinds of numbers, none of which mentioned in the RA9x user manual. thanks for your generous advice, -Gunther PS: But I do have one full SA600 rack with working drives and boy, it's pretty impressive firing this up. So many buttons to push and lights to monitor, it's fun. One drive contains VMS 7.2 and I'm sure lots of goodies, but I will not back those up. Once I've switched to UNIX I can try RAID with them :-). Does anybody know if the HSC90 by itself does RAID given a disk array and the proper configuration? -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
