Description
This document describes the procedure to delete a RAID volume on Sun Fire[TM] V215/V245/T1000/T2000 if there is no bootable Solaris[TM] Operating System installed



Steps to Follow
To create and delete RAID volumes normally it is recommended to boot into Solaris OS and use the 'raidctl' command.

However sometimes it is useful to be able to delete a volume while at the OBP level for troubleshooting or when there is no access to Solaris OS (for example when a system is being redeployed and you would like to remove the previously setup RAID devices before performing a clean installation). In these cases you can use the 'delete-volume' command at the OBP level to remove any unwanted volumes that are previously created.

follow these steps:
1. Set the auto-boot parameter to false, set the fcode-debug parameter to true and perform a reset-all:

{1} ok setenv fcode-debug? true
fcode-debug? =          true
{1} ok setenv auto-boot? false
auto-boot? =            false
{1} ok reset-all

2. After completing the reset, you need to select the controller that has the volume you wish to remove. If you do not know the controller you can use the 'show-disks' command to find it. Notice that the controller path is different on the different servers and that /disk is removed from the path used):

- for Sun Fire V215/V245:

{1} ok show-disks
a) /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk
b) /pci@1e,600000/pci@0/pci@1/pci@0/ide@1f/cdrom
c) /pci@1e,600000/pci@0/pci@1/pci@0/ide@1f/disk
q) NO SELECTION
Enter Selection, q to quit: q
{1} ok
{1} ok select /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1

- for Sun Fire T2000 using the PCI-X SAS controller:

{0} ok show-disks
a) /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/disk
b) /pci@7c0/pci@0/pci@1/pci@0/ide@8/cdrom
c) /pci@7c0/pci@0/pci@1/pci@0/ide@8/disk
q) NO SELECTION
Enter Selection, q to quit: q
{0} ok
{0} ok select /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2

- for Sun Fire T2000 using the onboard LSI1064E controller select the following path:

{0} ok select /pci@780/pci@0/pci@9/scsi@0

- for Sun Fire T1000 (dual-disk configuration is necessary for RAID) the disk controller path you'll need to select is:

{0} ok select /pci@7c0/pci@0/pci@8/scsi@2

3. After selecting the controller path, use the 'show-volumes' command to display the volumes that currently exist:

{1} ok show-volumes
Volume 0 Target 0  Type IM (Integrated Mirroring)
Optimal  Enabled
2 Members                                         143112591 Blocks, 73 GB
Disk 1
Primary  Online
Target 4        FUJITSU MAY2073RCSUN72G 0401
Disk 0
Secondary  Online
Target 1        FUJITSU MAY2073RCSUN72G 0401

4. Use the volume number from the previous step and the OBP command 'delete-volume' to remove the existing RAID volume. Please note that deleting the volume WILL DESTROY the data on the volume member drives:

{1} ok 0 delete-volume
The volume and its data will be deleted
Are you sure (yes/no)?  [no] yes
Volume 0 has been deleted

5. Use the 'show-volumes' command again to confirm that the volume has been properly deleted:

{1} ok show-volumes
No volumes to show

- you can then restore the NVRAM settings for normal operation:

{0} ok setenv auto-boot? true
{0} ok setenv fcode-debug? false
{0} ok reset-all

Please Note: Just like when you create a RAID volume, when you delete a RAID volume you need to boot into Solaris and use the format utility to label the disks so that they have proper labels for use by Solaris. In format choose each of the drives that were affected by the change, select 'type' then '0' (auto-config) and then 'label' for each drive to ensure they are properly labeled. Refer to  <Document: 1002561.1>  for more details. If there is no bootable Solaris OS on this system then you may boot single user mode off a dvd/cd or a Solaris network image to perform this action. e.g., 'boot net -s'
