Correlate WWN Device Names With Physical Locations (probe-scsi-all Command)

If you have access to the OS, you might be able to use the diskinfo command instead. See Correlate WWN Device Names With Physical Locations (diskinfo Command).

1. At the ok prompt, type

   {0} ok probe-scsi-all
   /pci@400/pci@1/pci@0/pci@c/LSI,sas@0 <===== SAS Controller
    
   FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.00.17.00
    
   Target 9
    Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
    SASDeviceName 5000c50033438dbb  SASAddress 5000c50033438db9  PhyNum 0 <=HD,slot 0
   Target b
    Unit 0   Disk   SEAGATE  ST930003SSUN300G 0468    585937500 Blocks, 300 GB
    SASDeviceName 5000c50005c15803  SASAddress 5000c50005c15801  PhyNum 1 <=HD,slot 1
   Target c
    Unit 0   Encl Serv device   SUN      NEM Hydra II SOL 0308
    SASAddress 5080020000bb193d  PhyNum 24
    
   /pci@400/pci@1/pci@0/pci@0/pci@0/usb@0,2/hub@3/storage@2
    Unit 0   Removable Read Only device    AMI     Virtual CDROM   1.00

2. In output, look for the following disk identifiers:

   • LSI,sas@0 – Controller (REM) on the server module.

   • SASDeviceName – WWN that the Oracle Solaris OS recognizes.

   • SASAddress – WWN that the OBP references.

   • PhyNum – Physical slot that the drive occupies.

3. Use the values in the output to construct the resulting Oracle Solaris logical device name as expressed by cntndn.

   This example is based on the previous output:

   • cn = c0

     where n is the SAS controller number, 0 in this example.

   • tn = t5000c50033438dbb

     where n is the SASDeviceName value.

   • dn = d0

     where n is 0 for all embedded SCSI devices.

   The resulting logical device name is c0t5000c50033438dbbd0.
