Drive power lost!

Drive power lost!

Drive power lost!

(OP)
Hi,
We've use Dell 4300 servers. On one of them we backup using Arcserve 6.5 every night
onto DAT. Sometimes when I return the following morning the log reports that there was an error due to tape drive power being lost and aborts the backup. We have tried replacing the drive and the scsi card, and have checked everything we can check, but we still get the same problem!

Any ideas?

RE: Drive power lost!

is the tape drive powered from a ups, if so plug it into the wall.  Also install the latest scsi card drivers from the vendor

RE: Drive power lost!

Is the tape drive a stand alone unit ? if so is it connected to a UPS ?  I have seen that a power spike of any kind will cause the tape drive to re-init and reset the scsi bus... once this happens arcserve will timeout communication to the thread being backup and fail the job.  hope this helps

RE: Drive power lost!

Change the scsi ribbon cable.....power spikes on internal tape drives hmmm don't think so m8.  And JemTCC thank you for repeating what i have already said.  You must work in management of something =:-]

RE: Drive power lost!

Is this fixed yet..? If not, I realise this is a bit of a long shot, but....

Are there any scsi disks on the same controller as the tape.? I have previously had a screwy problem where the disk activity just locked the bus to the tape drives and thus the software considered it to be powered down due to not etting a response on a query.

On the other hand, there is always the possibility that if you have extra disks (whether on the same controller or not!) and have a split power lead maybe the power supply is being overloaded and is intermittantly dropping power to the tape drive...
