Configuring a PowerPath Boot Device on Solaris
| 6. | Using a text editor such as vi, make the following changes to the |
|
|
| /etc/system file: |
|
|
| • Add this line above the forceload: drv/emcp statement: |
|
|
| forceload: drv/sd |
|
|
| • Add this line below the forceload: drv/emcp statement: |
|
|
| rootdev: /pseudo/emcp@6:a,blk |
|
|
| The /etc/system file now includes the following lines: |
|
|
| forceload: drv/sd |
|
|
| forceload: drv/emcp |
|
|
| rootdev: /pseudo/emcp@6:a,blk |
|
| 7. | Using a text editor such as vi, edit the /etc/vfstab file, |
|
|
| replacing each native partition (c#t#d#s#) for the boot device |
|
|
| with an emcpower partition name. In this example, you would |
|
|
| replace c1t6d0s0 with emcpower6a. You must change both the |
|
|
| /dev/dsk and /dev/rdsk entries. |
|
| 8. | Restart the host. Enter: |
|
|
| reboot |
|
|
|
| |
Recovery | If you cannot boot the host after configuring the PowerPath device as |
| |
Procedure | the boot device, you may have made a typing error when editing the |
| |
| /etc/system and /etc/vfstab files. To recover: |
| |
| 1. | Insert the Solaris Operating System |
|
|
|
| |
| 2. | At the ok prompt, enter: |
|
|
| boot cdrom |
|
| 3. | Mount the storage system boot device that is experiencing the |
|
|
| problem. For example, enter: |
|
|
| mount /dev/dsk/c1t6d0s0 /a |
|
| 4. | Enter: |
|
|
|
| |
|
| export TERM |
|
| 5. | Check the /etc/system and /etc/vfstab files against the |
|
|
| changes you made to these files when you set up multipathing to |
|
|
| the storage system boot device. Use a text editor such as vi to |
|
|
| correct any problems you find. |
