During a new cluster install of 5 HA(High Availability) pairs with internal shelfs only 4 shelfs are reporting instead of 5
One Shelf reports paths to 4 nodes instead of 2 nodes as seen by command STORAGE SHELF SHOW -CONNECTIVITY

Duplicate WWN & midplane serial number found under ENVIRONMENT logs for each node in 2 separate HA pairs involved

Enclosure information: [1] WWN: XXXXXXXXXXXX7a5d Shelf ID: 00 Serial number: xxxxxxxxxxxx0028 Part number: xxx-xxxxx+xx Midplane serial number: xxxxxxxxx059 Midplane part number: xxxxxxxxx+xx

Enclosure information: [1] WWN: XXXXXXXXXXXX7a5d Shelf ID: 00 Serial number: xxxxxxxxxxxx0030 Part number: xxx-xxxxx+xx Midplane serial number: xxxxxxxxx059 Midplane part number: xxxxxxxxx+xx

Checking ENVIRONMENT logs we can see that the ES ELECTRONICS INFORMATION shows different serial numbers per node in each HA pair as expected:
