We experienced a rackmounted NSR M2402 reboot during our backups lastnight, this is not the first time it has happened.

The errors logged are as follows:

This caused 11 backup jobs to fail overnight.

The NSR and backup server are zoned correctly into an HP Coreswitch 2/64 Fibre switch running 5.0.5a

The Server attaches to the NSR via an FCA2101 HBA running 1.70a1 and 3.92a2

The MSL5026SL and MSL5052SL are running 0516 and the SDLT110 drives are running V85.

Thanks,

Alun.

Re: NSR Reboots during backups

SK/ASC/ASCQ codes suggest it might have started with a medium error/write error from an attached drive (3/2/4/0 ?).

Do you have any errors reported from any of the drives ?. Do you have support tickets ??
Is it possible to trace if the same media was used on previous occurances ??
