On AIX 7, use the command cfgmgr without arguments to rescan the HBA for new LUNs.


# cfgmgr

Use "odmget" to correlate the serial number to the volume on Pure:


root@hclaix:~# odmget -q "name=hdisk26 and attribute=unique_id" CuAt
CuAt:
 name = "hdisk26"
 attribute = "unique_id"
 value = "3A213624A937018563310400CACD7000115F10AFlashArray04PUREfcp"
 type = "R"
 generic = ""
 rep = "nl"
 nls_index = 79

Run the following on the Everpure FlashArray to verify the serial number matches:


$ purevol list
