Right. So if only NAS, disable it. It’s only for SAN kernel quorum and automatic failover when OOQ. Storage failover (SFO) is different and is viewed via "storage failover show.” You do want SFO enabled.

 

One of the clusters might have had it enabled as a holdover from a previous upgrade, or perhaps you had SAN enabled at one time.

They are both 8.2.3P1

So that failover is for SAN only?

Neither cluster has FC or iSCSI enabled

 

thanks

That is for failover due to KCS being OOQ. Basically, if a node goes out of SAN quorum, it reboots. 

 

What releases are your two clusters on? May just be a change in the default behaviors.

Anyone have a 4-node 2240 cluster running 8.2.x?

 

If so, could you tell me if failover says enabled or disabled when you do a “cluster kernel-service show” in diag mode.

I’ve had a performance case open for months on this cluster and I noticed recently that this cluster says failover is disabled but our 4 node 3220 cluster says enabled.

 

LCNA2::> set d

Do you want to continue? {y|n}: y

 

LCNA2::*> cluster kernel-service show
