Probe-Scsi-All Device Naming (Openboot) - Oracle SPARC Administration Manual

probe-scsi-all Device Naming (OpenBoot)

probe-scsi-all Device Naming (OpenBoot)
The output displayed by probe-scsi-all lists all SCSI devices in the server and provides
a basic set of information about each device. When analyzing the probe-scsi-all output,
look for the following data fields that are different names for the same device. You must use a
specific type of name in different commands.
Entity Name
Target
SASDeviceName
SASAddress
PhyNum
VolumeDeviceName (when a RAID volume is
configured)
VolumeWWID (when a RAID volume is configured)
At a high level, the WWN mapping process consists of the following stages:
1. Identify the physical location of the hard drive that is to be the target of the operation.
2. Identify the controller port that is attached to that physical location.
3. Find the WWN-based device name of the drive attached to that controller port.

Definition
Each SAS or SATA drive is assigned a unique target ID.
The WWN value assigned to a SAS drive by the
manufacturer. Oracle Solaris recognizes this name.
The WWN value assigned to a SCSI device that is
recognized by the OpenBoot firmware.
A hexidecimal ID of the controller port that is attached to
the target drive.
The WWN value assigned to a RAID volume that is
recognized by Oracle Solaris. The VolumeDeviceName
replaces the SASDeviceName of every SCSI device
contained in the RAID volume.
Use the VolumeDeviceName entity to determine the correct
target in a RAID volume, or when the server is configured
with an optional internal RAID HBA controller.
The WWN-based value assigned to a RAID volume that
is recognized by the OpenBoot firmware. VolumeWWID
replaces the SASAddress of every SCSI device contained in
the RAID volume.
