MSL5026 Always going offline/online on the Severs connect to SAN

My tape Library MSL5026 is Always going offline/online on the Severs connect to SAN.
The Data-Router and SAN Switch dont have any erors. And the cables are OK.

Thanks,

Hi Miguel.

I need a little more information from you.

Are you using an embedded NSR on the MSL5026, or is this the M2402 NSR?

There is a firmware update for either NSR that resolves an issue where drives/robotic arm would disappear and reappear.

The problem firmware was: 4.03.16

The newest firmware for the M2402 is: 4.03.21

Hopefully that is where your problem is, and you can just upgrade and be done!

Miguel,
check:
1. FC drivers, their settings (regisrty parms). Which HBA do you use?
2. switch: porterrshow output (check for CRC and 'enc in' errors for NSR connected port);
3. NSR log if it logs reboots.
BTW, does it happen for SAN connected disks if there are any?

I have a MDR (Module Data Router) with one fiber port and two SCSI ports.

I made the firmware upgrade and it fix the problem.

Thanks
