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.
|
|
Target |
Each SAS or SATA drive is assigned a unique target ID. |
SASDeviceName |
The WWN value assigned to a SAS drive by the manufacturer. Oracle Solaris recognizes this
name. |
SASAddress |
The WWN value assigned to a SCSI device that is recognized by the OpenBoot firmware. |
PhyNum |
A hexidecimal ID of the controller port that is attached to the target drive. |
VolumeDeviceName (when
a RAID volume is configured) |
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. |
VolumeWWID (when a
RAID volume is configured) |
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. |
|
At a high level, the WWN mapping process consists of the following
stages:
Identify the physical
location of the hard drive that is to be the target of the operation.
Identify the controller port that is attached to that physical location.
Find the WWN-based device name of the drive attached to that controller port.
Note -
Refer to the service manual for the server for a description of the physical drive
slot organization.
