Applies to

  • AFF systems
  • NS224 NVMe SSD shelf with NSM100 modules

Answer

  • SAS disk shelf connectivity can be viewed with sasadmin expander_map or SAS-EXPANDER-MAP section in Active IQ.
  • For the NS224 NVMe SSD shelves attached to AFF systems, there is no direct equivalent to show NVMe shelves and paths.
  • The closest equivalent is to view disk path names to determine the connectivity between AFF nodes and NS224 shelves. 
    • CLI: storage disk show -fields diskpathnames
    • See Active IQ section STORAGE-DISK.XML.
Disk Name   8.70.5  
Container Name

node_01_NVME_SSD_1

node_02_NVME_SSD_1

  • ​​​​​The node and node Ethernet storage port are listed under List of Path-Based Disk Names.
  • A path disk name is in this format: Node:EthernetPort:ShelfID:PathID:BayID
    • Path ID maps to the Ethernet ports on the NSM100 modules in the NS224 shelf:
      • 0 = Module A, e0a
      • 1 = Module A, e0b
      • 2 = Module B, e0a
      • 3 = Module B, e0b
