Correlate WWN Device Names With Physical Locations (probe-scsi-all Command)
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).
■
Look at the values in this output to construct a logical device name in the
3.
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.
