I have been trying to perform an NDMP backup between A HP LTO5 Ultrium Tape Library and Netapp with the MDS switch providing the fabric.
However, everytime I initiate the job, I experience this problem.
Below are some of the outputs on the concerned FC Ports:
MDS-SW01# sh int fc1/27
fc1/27 is down (Error disabled - bit error rate too high)
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
Port WWN is 20:1b:54:7f:ee:e2:8d:00
Admin port mode is auto, trunk mode is on
snmp link state traps are enabled
Port vsan is 2
Receive data field Size is 2112
Beacon is turned off
5 minutes input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
5 minutes output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
263045 frames input, 12907156 bytes
0 discards, 0 errors
0 CRC, 0 unknown class
0 too long, 0 too short
4308477 frames output, 8677425352 bytes

What could be causing the issue and what is the solution?!
Thanks.
