Identifying Drive Logical Device Names and Physical Locations

The Oracle Solaris OS now uses the worldwide number (WWN) in place of the target ID field (tn) in drive logical device names for SAS-2 storage controllers.This change affects how you correlate a drive's logical name with the drive's physical location.

These points are key to understanding the impact of this change:

To correlate drive logical device names with physical locations or the other way around:

Correlate WWN Device Names With Physical Locations (diskinfo Command)

The diskinfo command, a new disk and slot identification utility, was introduced in Oracle Solaris 10 8/11 OS and in the kernel patch 144500-19 (or later).

If you do not have access to the OS, for example, if the server module is not booted, see Correlate WWN Device Names With Physical Locations (probe-scsi-all Command).

If your OS does not provide the diskinfo command, refer to the SPARC and Netra SPARC T4 Series Servers Administration Guide for alternative methods.

  1. Log into the OS.
  2. Type:
    # diskinfo -a
    Enclosure path:         1114BD0ACC-physical-hba-0
    Chassis Serial Number:  1114BD0ACC-physical-hba-0
    Chassis Model:          ORCL,SPARC-T4-1B
    Label      Disk name               Vendor   Product          Vers
    ---------- ----------------------  -------- ---------------- ----
    /SYS/HDD0  c0t5000C50033438DBBd0   SEAGATE  ST930003SSUN300G 0B70
    /SYS/HDD1  c0t5000C50005C15803d0   SEAGATE  ST930003SSUN300G 0468
  3. Use the output under the Label and Disk Name columns to correlate a drive's physical location with its corresponding logical device name.

    For this server module:

    • /SYS/HDD0 represents a drive in slot 0.

    • /SYS/HDD1 represents a drive in slot 1.

    In this example, the drive installed in slot 0 has a logical device name of c0t5000C50033438DBBd0.

    Note - The diskinfo command provides a variety of disk information depending on the command options you specify. For more information, type diskinfo -h and refer to the diskinfo(1M) man page.

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

If you have access to the OS, you might be able to use the diskinfo command instead. See Correlate WWN Device Names With Physical Locations (diskinfo Command).

  1. At the ok prompt, type:
    {0} ok probe-scsi-all
    /pci@400/pci@1/pci@0/pci@c/LSI,sas@0 <===== SAS Controller
    FCode Version 1.00.54, MPT Version 2.00, Firmware Version
    Target 9
     Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
     SASDeviceName 5000c50033438dbb  SASAddress 5000c50033438db9  PhyNum 0 <=HD,slot 0
    Target b
     Unit 0   Disk   SEAGATE  ST930003SSUN300G 0468    585937500 Blocks, 300 GB
     SASDeviceName 5000c50005c15803  SASAddress 5000c50005c15801  PhyNum 1 <=HD,slot 1
    Target c
     Unit 0   Encl Serv device   SUN      NEM Hydra II SOL 0308
     SASAddress 5080020000bb193d  PhyNum 24
     Unit 0   Removable Read Only device    AMI     Virtual CDROM   1.00
  2. In output, look for the following disk identifiers:
    • LSI,sas@0 – Controller (REM) on the server module.

    • SASDeviceName – WWN that the Oracle Solaris OS recognizes.

    • SASAddress – WWN that the OBP references.

    • PhyNum – Physical slot that the drive occupies.

  3. Use the values in the output to construct the resulting Oracle Solaris logical device name as expressed by cntndn.

    This example is based on the previous output:

    • cn = c0

      n is the SAS controller number, 0 in this example.

    • tn = t5000c50033438dbb

      n is the SASDeviceName value.

    • dn = d0

      n is 0 for all embedded SCSI devices.

    The resulting logical device name is c0t5000c50033438dbbd0.

Oracle Solaris Jumpstart WWN Syntax

The Oracle Solaris syntax requires all WWN alpha characters to be capitalized.

Note - Only the WWN portion of the logical device name requires capitalized alpha characters. The c0 and d0 portion are not capitalized.

This Jumpstart profile example shows how to use the WWN syntax when installing the OS on a specific drive.

Interactive Installation Example

In an interactive installation, you are asked to specify one or more drives as the targets for the OS installation. This step ensures that sufficient storage capacity is provided for the installation. Specify the drive with the WWN value that corresponds to the drive on which you want to install the software.

These WWN values are illustrated in the following interactive example. The drive selected as the installation target is located in drive slot 0, the default boot location.

Note - If you prefer to use some other disk, specify it instead of the one in HDD slot 0.

_ Select Disks_________________________________________________________________
On this screen you must select the disks for installing Solaris software. Start
by looking at the Suggested Minimum field; this value is the approximate space
needed to install the software you've selected. Keep selecting disks until the
Total Selected value exceeds the Suggested Minimum value.
