FAS8080 Flex Array - OCUM warning: Disk Shelf Multipath Not Configured

J-L-B

I have a FAS808EX (OnTap 8.3.2p4) configured as a FlexArray only.  No local attached disk shelves.  The OS boots off another array lun on each node.  1 aggregate is configured on each node with array luns on the same array.  

 

All is running well except OCUM 7 is reporting a warning on both nodes:  Disk Shelf Multipath Not Configured.  Being that there are no local disk shelves, is this something that can be turned off?  The only way to get it to go away on OCUM 7 is to turn off the multipath alerts globally which I don't want to do because I have other nodes on this same cluster and other clusters.

 

Here's the alert from OCUM:

 

Severity:  Warning
State:  Acknowledged
Impact Level:  Risk
Impact Area:  Availability
Source:  cluster1_01
Acknowledged By:  ocumadmin (44 Mins Ago)
Resolved By:  
Assigned To:   
Triggered Time:  1 Hour 5 Mins Ago
Trigger Condition:  Disk shelf has either one or no path connected to the node.

Hi @J-L-B

 

It might be the false alert with OCUM, even i am facing the same issue. Please open a support case with netapp.

After contacting support, this issue is due to an OS bug. Bug ID 927715

 

Although the system is healthy, per their response:  "There is no fix until 9.2 OS is released, till then you need to keep ignoring these alerts."

I cannot find that BUG IN on Netapp Bug Tools.  Nothing came up when I search for that BUG ID.

Is there any more information on this bug, publically?

 

Is it confirmed fixed in 9.2?

Re: FAS8080 Flex Array - OCUM warning: Disk Shelf Multipath Not Configured

I have not seen it listed in the fixes included in 9.2 and I haven't brought those Flex Array FAS8080 nodes up to that level yet to check if it was resolved.  Going to let 9.2 vet itself out a little longer.

 

I did however check all of the 9.1 patches and bug fixes and they don't have anything that looks related:

http://mysupport.netapp.com/NOW/download/software/ontap/9.1P1/

through

http://mysupport.netapp.com/NOW/download/software/ontap/9.1P6/


There's nothing mentiond here:
http://mysupport.netapp.com/NOW/download/software/ontap/9.2/

 

There's also no further mention of it here: 

https://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=927715

 

If anyone else knows please let us know.

I have a customer with a new FAS2650 running ONTAP 9.2 and OCUM 7.2 and the error ist still there... 

Therefore I can confirm this bug is not fixed yet.

This issue was resolved for me with OCUM 7.2 P1

We are running OCUM 7.1P2 and 2xFAS2650 HA-Cluster with NetApp Release 9.2P1 and the warning still exists although there are no errors in "system health alert show"

Just to reconfirm, this fix requires 7.2P1 (not 7.1P2)

Re: FAS8080 Flex Array - OCUM warning: Disk Shelf Multipath Not Configured

J-L-B

Confirmed this is fixed in OCUM 7.2P1.  Upgraded this week from 7.0 to 7.2P1 and cleared all events.  

 

The warning: ""Disk Shelf Multipath Not Configured" did not reoccur for the multiple FlexArrays installed.
