We have got this request:
Recently we have noticed that some of our fiber optic cables have degraded, this is sadly not reported anywhere else exept with the commands below…
STOR04-A1::*> storage port show -node STOR04-A1-01 Speed Node Port Type (Gb/s) State Status ------------------ ---- ---- ------ -------- --------------- STOR04-A1-01 0a SAS 6 enabled online 0b SAS 0 enabled offline 0c SAS 6 enabled online-degraded 0d SAS 0 enabled offline 3a SAS 0 enabled offline 3b SAS 6 enabled online 3c SAS 0 enabled offline 3d SAS 6 enabled online 6a SAS 12 enabled online 6b SAS 12 enabled online 6c SAS 12 enabled online 6d SAS 12 enabled online 12 entries were displayed.The cable in question is a QSFP copper to optical LC and is used because the disk shelfs are located in another server room. As you can see from the details above it is degraded, and this is most likely because of dust on the connectors.
The system itself also doesn’t see any errors… (the system health commands all report OK) and the disk paths are also all online.
Do you have a plugin catching this before we loose the connection?
Solution: A Storage Port Check
Yes we can ;-) We have developed a plugin that goes trough the list of all storage ports and alarms if at least one of them is not online. With the optional --ok-status=<regex> parameter, this rule can be changed to whatever you want. E.g. --ok-status="^(on|off)line$" would allow also offline storage ports for an ok-result.
Examples
$ check_netapp_storageport -H filer
NETAPP STORAGE PORT CRITICAL - 9 storage ports checked, 4 CRITICAL
filercluster-01.v2: offline (CRITICAL)
filercluster-01.v7: offline (CRITICAL)

filercluster-01.v3: offline (CRITICAL)
filercluster-01.v5: online
