Backing Out on a Diskless Client or Solstice AutoClient from a Server

To back out the Solaris 7 MU3 software on a diskless client or AutoClient system from a server using backout_mu:

1. Halt the diskless client or AutoClient system.

2. Determine whether you must back out special patches.

   • If you did not install special patches on a diskless client or Solstice AutoClient system as described in "Installing Special Patches" , go to Step 3 to complete the backout.

   • If you installed special patches on a diskless client or Solstice AutoClient system, as described in "Installing Special Patches", you must back out the special patches by typing the following command for each of the patches:

     # patchrm -R /export/root/client_name patch_id

     where client_name is the hostname of the diskless client or AutoClient system and patch_id is the ID of the special patch.

3. On the server, run the backout_mu script located in the local product directory, with the client's root directory as the argument.

   • From a local copy of the MU3 image that corresponds to the client platform, type:

     # cd local_directory # ./backout_mu -R /export/root/client_name

     where client_name is the hostname of the diskless client or AutoClient.

   • From the MU3 CD, mount the CD and type:

     # cd /cdrom/s7_maintenance_update_3_platform # ./backout_mu -R /export/root/client_name

     where platform is sparc or x86 and client_name is the hostname of the diskless client or AutoClient system.

4. Repeat this process for each diskless client or AutoClient sytem being served.

5. Determine whether you must back out special patches.

   • If you did not install special patches on a server's service area, as described in "Installing Special Patches" , go to Step 6 to complete the backout.

   • If you installed special patches on a server's service area, as described in "Installing Special Patches", you must back out the special patches by typing the following command for each of the patches:

     # patchrm -S Solaris_2.7 patch_id

     where patch_id is the id of the special patch.

6. Back out the Solaris 7 MU3 software on the server's service area. From a local copy of the MU3 image that corresponds to the service area being patched, type:

   # cd local_directory ./backout_mu -S Solaris_2.7

   Note -

   If a service area is shared by the server, you also need to remove the same Maintenance Update patch set from the server's root area. Failure to do so will result in an unstable and improperly patched server.

7. Boot the diskless client or AutoClient system.
