Solved: Error disabled - bit error rate too high on MDS switch

fredrickchisanga · ‎10-15-2014

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

32 receive B2B credit remaining

0 transmit B2B credit remaining

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

Thanks.

hi,

If SFPs have been replaced, it's time for the cables and patch-panels.

Is this the same problem, as discussed under

https://supportforums.cisco.com/discussion/12322531/cisco-mds-switch-port-unavailable ??

and

https://supportforums.cisco.com/discussion/12322021/nexus-5548-lto3-tape-drives-interface-down

Please provide a drawing of the configuration, with

- FC port type, speed, medium (show interface of every FC port, tape as well as Netapp)

- show flogi database

- is there a FC speed mismatch between tape and Netapp ?

Hi wdey,

This is same case as https://supportforums.cisco.com/discussion/12322531/cisco-mds-switch-port-unavailable!

Admin port mode is auto, trunk mode is on

Tape Data:

The info for the tape Library has been a challenge to retrieve, however, Documentation states that the FC Port can support upto 4GB. On the SL Console, it is showing that it is in Auto! With N_mode.

We set the speed on the MDS switch to 4GB on the port where the tape library is connected, hoping to address the speed mismatch, but still had same issue!

Here are some of the logs off the MDS switch!

The error log file is full of events, like

2014 Oct 13 06:41:43 --MDS-SW01 %PORT-4-IF_SFP_WARNING: Interface fc1/18, Low Rx Power Warning
2014 Oct 13 06:41:43 --MDS-SW01 %PORT-3-IF_SFP_ALARM: Interface fc1/18, Low Rx Power Alarm

followed by interface down / up,........

I see this for interface 1/19, 1/20, 1/18, 1/10, 1/25, 1/26.

The traffic flow is not going directly from disk (Netapp) to tape, but disk (Netapp) - Backup server - Tape ? correct ?

RX power warning : either you have wrong (single mode) patch cables; dirty connectors; broken SFP's; something at the physical layer is wrong.

If this is not fixed, you will have problems.

fredrickchisanga · ‎10-16-2014

The traffic flow is flowing directly from disk (Netapp) to tape, through the Fabric (MDS). The two are zoned, accordingly. The type of traffic involved is NDMP data!

We will look at the physical layer and try to address the Rx Power warning, thank you for pointing that out.

Any word on the 'errDisable'?!

Walter Dey · ‎10-16-2014

I think once you have fixed the physical problems (RX power issues), error disable will be gone.

fredrickchisanga · ‎10-16-2014

I do not see any such errors on the ports that are involved in the design! I.e ports 23 and 27 or 28!

Do you suggest the Rx issue is system wide?!

Kindly advise the main suspects with the ErrDisable error?! The possible causes.

Walter Dey · ‎10-16-2014

The following ports show RX power alarms:

FC 1/20, 1/12, 1/18, 1/10, 1/19

Can you please post the transceiver details ? show int fc1/28 transceiver

Cisco SFP's parts ? are the patch cables MMF ?

Walter Dey · ‎10-17-2014

Are your patch cables MMF 50/125 or 62.5/125 ?

fredrickchisanga · ‎10-17-2014

Hi the cable is MMF 50/125! Any line of thinking?!

Walter Dey · ‎10-17-2014

That's ok (max 50 m); do you have any sharp bend radius ?

fredrickchisanga · ‎11-02-2014

Sorry wdey,

I was away for a while.

There are no sharp bends, that we have noticed.

fredrickchisanga · ‎11-27-2014

Hey,

I tried change of SFPs from Finisar to Cisco Shortwave to not much effect! Only improvement was that a little more data was transferred (initially 50 GB now 250 GB) before the link drop!

Any thoughts?

guijarro_felipe · ‎12-16-2014

hi,

If SFPs have been replaced, it's time for the cables and patch-panels.
