Creating an Alias for a Bootable Drive (SPARC)

This section describes how to create an alias for a bootable drive in order to help simplify the process of booting the drive. This section contains the following topic:

To Create an Alias for a Bootable Drive (SPARC)

Perform the steps in this section to help simplify the process of booting a drive on a SPARC system.

1. Issue the show-disks command to list the disks on the system.

   Note that, as shown in the following example, you can determine the HBA drives by looking for the LSI,sas@number label, where number is 0 for the first HBA detected, and increments for each additional HBA detected.

   {0} ok show-disks
   <...>
   a) /pci@1e,600000/pci@0/pci@3/LSI,sas@0/disk
   b) /pci@1e,600000/pci@0/pci@3/LSI,sas@1/disk
   c) /pci@1e,600000/pci@0/pci@3/LSI,sas@2/disk
   <...>
   q) NO SELECTION
   Enter Selection, q to quit: 
   

2. Select the bootable drive for which you want to create an alias.

   a) /pci@1e,600000/pci@0/pci@3/LSI,sas@0/disk
   b) /pci@1e,600000/pci@0/pci@3/LSI,sas@1/disk
   c) /pci@1e,600000/pci@0/pci@3/LSI,sas@2/disk
   <...>
   q) NO SELECTION
   Enter Selection, q to quit: c
   /pci@1e,600000/pci@0/pci@3/LSI,sas@2/disk has been selected.
   

3. Use the nvalias alias-name HBA-drive-path command to create an alias for the bootable drive that you selected in Step 2 (you can press Ctrl+Y to paste the device path).

   In the following example, the alias name is mydev.

   {0} ok nvalias mydev /pci@1e,600000/pci@0/pci@3/LSI,sas@2/disk
   

4. You can now boot from the bootable drive by using the boot alias-name command.

   {0} ok boot mydev
   

5. To optionally add the bootable drive to the boot-device list and then automatically boot from the drive by controlling the boot device order, issue the following commands, as shown.

   {0} ok printenv boot-device
   boot-device = disk0 disk1
   {0} ok setenv boot-device mydev disk0
   boot-device = mydev disk0
   

   In this example, the mydev alias is set as disk0, the first disk in the boot device list. This results in the automatic booting of the bootable drive, /pci@1e,600000/pci@0/pci@3/LSI,sas@2/disk.

6. Validate the label of the bootable drive by following the steps in Validating the Label of the HBA Drive.
