Bare-Metal Recovery : Solaris Bare-Metal Recovery - Preparing for an Interactive Restore (part 2) - Bare-Metal Recovery with Flash Archive

Bare-Metal Recovery with Flash Archive

Now that we’ve created a flash archive image, let’s use it to perform an interactive restore of a Solaris system. To do this, perform the following steps:

1. First, ensure that the system is powered on and that it is at the ok> prompt.

2. If you are unsure whether your boot and recovery devices are available, you can ensure they are by performing a probe:

3. ok> probe-scsi-all

4. A list of locally attached devices should be displayed. Ensure that at the minimum, the local boot disk, a CD/DVD drive (if applicable), and the correct SCSI tape drives are listed.

5. If you plan to restore from tape, insert the tape into a local tape drive.

6. Boot the system:

7. 1. If you are booting from CD, insert the Solaris Installation CD into the appropriate device on the system you want to restore and enter boot cdrom at the ok> prompt.

   2. If you have a network boot server configured, you may also boot from the network using the boot net – install command.

8. The system then boots, and you are taken through the standard Solaris installation prompts. Once you reach the Specify Media prompt, select 5 to restore from local tape, or 2 to restore from an NFS mount.

9. 1. If you select tape, you are prompted for the tape device name and the tape file in which the image is located. Remember that 0 is the first file on the tape.

   2. If you select NFS, you are prompted for the name of the NFS server and share where your flash archive images are located. You will then need to select an image from the images it finds there.

10. You are then prompted for the name of the disk you wish to restore to and asked how you would like it partitioned. Answer the prompts according to your environment.

11. Once those steps are done, the recovery should complete automatically, followed by a reboot.

An interactive recovery example

The following example restores an image from tape. If your images are on disk, you would select option 2 instead of option 5.

Please specify the media from which you will install the Solaris Operating
Environment.

Media:

1. CD/DVD
2. Network File System
3. HTTP (Flash archive only)
4. FTP (Flash archive only)
5. Local Tape (Flash archive only)

   Media [1]: 5

Please specify the local tape device and the position on the tape where the
Flash archive is located.

To select a different media, enter B to go Back.
   Tape Device or B [/dev/rmt/0] /dev/rmt/0n
   Tape Position or B [1] 0

You selected the following Flash archives for initial install:

 Tape  /dev/rmt/0n      0

Press Return to continue or enter D to deselect all archives: <enter>

To select additional Flash archives, please specify the media where the
archives are located.

Media:

1. CD/DVD
2. Network File System
3. HTTP
4. FTP
5. Local Tape
6. None - Archive Selection Complete

If there are archives that contain additional filesystems, you can specify them here.

Select which disks you want to lay out the file systems on.
Available Disks:
   Disk      Size

Enter 'y' to layout file systems on the specified disk.  This will erase all
existing data on the disk.  Enter 'n' to leave the disk unmodified.  Enter 'e'
to leave the remaining disks unmodified and continue with install.

Layout file systems on disk c0t0d0 (bootdisk) (y/n) [y]? y

At least one of the disks selected for installing Solaris software has file
systems or unnamed slices that you can choose to preserve. Do you want to
preserve existing data?

Enter y to preserve data or n to skip data preservation. [n] <enter>
