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

1. At the OpenBoot prompt, type:

   ok probe-scsi-all
   /pci@302/pci@2/pci@0/pci@14/LSI,sas@0

     Unit 0   Disk   HGST     H101860SFSUN600G A3T0    1172123568 Blocks, 600 GB
     SASDeviceName 5000cca02f02b138  SASAddress 5000cca02f02b139  PhyNum 6 
   Target 10 
     Unit 0   Disk   HGST     H101860SFSUN600G A3T0    1172123568 Blocks, 600 GB
     SASDeviceName 5000cca02f028fd0  SASAddress 5000cca02f028fd1  PhyNum 7 
   
   /pci@300/pci@1/pci@0/pci@2/usb@0/storage@1
     Unit 0   Disk     smiMICRON  eUSB DISK       1112

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

     where n is the SAS controller number.

   • tWWN = t5000cca02f0256b8

     where WWN is the SASDeviceName value.

   • dn = d0

     where n is 0 for all embedded SCSI devices.

   The completed logical device name is c0t5000cca02f0256b8d0.
