Re: Tape device no more recognized

Thnak you guys,

it was only all about a power connection problem... Now the tape is visible!

By the way.. we disconnected the SCSI cables when both server and tape devices were down, so no problem about hw problems nor any pin damaged.

Thanks

Re: Tape device no more recognized

Does ioscan -f show the SCSI card? The -C tape option will indeed filter out everything that is not a tape. I have been fairly lucky in changing cables with power on -- it only fails every 20 times or so. This must have been your time to fail. The high density SCSI connectors are very prone to bent pins and forcing a SCSI connector almost always crushes one or more pins. Occasionally you can straighten them successfully but most of the time, you have to replace the cable, or worse, the I/O card.

Re: Tape device no more recognized

Such bent pins can be terrible.

First you are not sure (you cannot see) if they are really bent or not.

Then this may produce very strange behavior - tape is visible from boot console, but not from OS, it is visible but not working, not visible at all, working but slow, etc ... nasty.

Hope this helps!

Torsten.
