We have discovered a serious bug in the DPT firmware, Version 7L0. It manifests itself in the following manner (at least): * On Single Ended controllers; The ``Shelf Good'' signal reaches the DPT from the disk bay, but the HBA equivalent (HBA Good) does not reach the disk bay. As a result, the fault light remains on, and the disk cassettes will erratically display the fault light. * On differential controllers connected via Diff-SE adaptor; A whole bus will seem to have disappeared. If you struggle with the cables, you MAY see it for a while, but it will not survive a re-boot. Solution: Roll back to (ar stay at) the 7H firmware. I have posted 7H3 firmware in ftp://sendero-ppp.i-connect.net/crash/476d07h3.fwi There are no restrictions on downloading it. We know of this problem with several StorageWorks disk bays, ours included. We have not tested it with other disk bays, and drives which are directly connected are NOT effected. We will post a new firmware once we get it from DPT and veify proper operation. Hope this helps. --- Sincerely Yours, (Sent on 23-Sep-97, 15:12:42 by XF-Mail) Simon Shapiro Atlas Telecom Senior Architect 14355 SW Allen Blvd., Suite 130 Beaverton OR 97005 Shimon@i-Connect.Net Voice: 503.643.5559, Emergency: 503.799.2313
