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

1. At the OpenBoot prompt, type:

   ok probe-scsi-all

   Target 10 
     Unit 0   Disk   HGST     H101860SFSUN600G A3T0    1172123568 Blocks, 600 GB
     SASDeviceName 5000cca02f028fd0  SASAddress 5000cca02f028fd1  PhyNum 7

     Unit 0   Disk     smiMICRON  eUSB DISK       1112

2. In the probe-scsi-all output, find the following disk identifiers:

   • LSI,sas@0 – Disk controller, followed by its associated target drives with their Target IDs. 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. Use the values in the probe-scsi-all output to construct a logical device name in the cntWWNdn format that is recognized by Oracle Solaris.

   For the example output, you can construct an Oracle Solaris device name for the drive in slot 0, indicated with PhyNum 0, as follows:

   • cn = c0

     n is the SAS disk controller number.

   • tWWN = t5000cca02f0256b8

     WWN is the SASDeviceName value.

   • dn = d0

     n is 0 for all embedded SCSI devices.

   The completed logical device name is c0t5000cca02f0256b8d0.
