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

1. At the OpenBoot prompt, type:

   ok probe-scsi-all
   /pci@400/pci@1/pci@0/pci@cLSI,sas@0
    
   FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.00.17.00
    
   Target 9
    Unit 0   Disk   SEAGATE   ST9300003SSUN3006 0B70   585937500 Blocks, 300 GB
    SASDeviceName 5000c50033438dbb  SASAddress 5000c50033438db9  PhyNum 0
   Target b
    Unit 0   Dusj   SEAGATE  ST930003SSUN300G 0468   585937500 Blocks, 300 GB
    SASDeviceName 5000c50005c15803  SASAddress 5000c50005c15801  PhyNum 1
   Target c
    Unit 0  Elcl 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 this output, look for these disk identifiers:

   • LSI,sas@0 – Disk controller (a REM in this example). If the server has more than one disk controller, the target drives associated with each controller are listed following that controller's information.

   • SASDeviceName – WWN that Oracle Solaris recognizes.

   • SASAddress – WWN that OpenBoot references.

   • PhyNum – Physical slot that the drive occupies (the value 0 indicates a drive in HDD slot 0).

3. Look at the values in this output to construct a logical device name in the cntWWNdn format that is recognized by Oracle Solaris.

   For this example, you construct a name like this to indicate the drive in slot 0.

   • cn = c0

     n is the SAS controller number.

   • tWWN = t5000c50033438dbb

     WWN is the SASDeviceName value.

   • dn = d0

     n is 0 for all embedded SCSI devices.

   The completed logical device name is c0t5000c50033438dbbd0.
