[PCA 2.x] Creating Custom Storage_Networks Using the PCA-ADMIN Interface Can Improperly Set the Cluster Resource Value (Doc ID 2872508.1)

Last updated on JANUARY 12, 2024

Applies to:

Private Cloud Appliance - Version 2.4.3 to 2.4.4 [Release 2.0]
Linux x86-64

Symptoms

PCA 2.4.3 and PCA 2.4.4 both allow for the creation of custom storage networks that allow the VM's direct access to NFS on the internal ZFSSA in a PCA X8.  The command needed to create these is documented in the administration guide.  The end result of the command on the ZFSSA is a new vnic is created.  A vnic will have the ZFSSA cluster resource ownership value set to the head where the vnic was created.  If SN02 is the active node of the ZFSSA cluster when the PCA-ADMIN commands are run, a new vnic owned by SN02 will be created. 

The data pool on a PCA is owned by SN01.  This can mean if a failback is issued, the data pool and the vnic will be sent to different heads and cause a disruption to the availability data traffic on the new storage network.
