Hi I have recently taken over an aging network and am encountering a problem with ArcServe connecting to the backup device - error reads status offline however Windows can detect the device in device manager ok
Device and OS
Server - Dell PowerEdge 2650
Windows Server 2003 Standard SP2
ArcServe v11.5 SP4
Dell PowerVault 136T
Contains SCSI -> Fibre module
Dell EMC Fibre Switch
Every now and then Arcserve is unable to detect the device - error reads status offline. To resolve this in the past I have powered off the tape library and fibre switch for about 30 minutes. Then shut down the Server and powered up the Fibre switch, then the Tape Library. Waited for the tape library to display online in the LCD display then powered up the Server. Normally ArcServe detects the device and I can use as normal. Sometimes Arcserve does not detect after a restart and I restart the ArcServe Tape service in Windows admin tools afew times before the device is detected. One other time I left all devices on over night with the status offline error and by morning the deives status changed to online without any further intervention.
There are no errors in windows, arcserve or on the tape library. The tape library is over 5 years old and Dell will not extend the warrantee however they have run a complete service and diagnostics, upgraded all the latest firmware and drivers and were unable to find any faults or errors.
At present Arcserve is showing deivce offline and I cannot run the backup. I am going around in circles restating each device without being able to resolve at the root cause. Any ideas would be appriciated.
