Multiple install types for same fileset --------------------------------------- The following filesets have both a base-level and an update fileset on the installation media at the same level. Since they have the same name and level, the last fileset on the installation media will be used.

These are the estimated resources required for the entire operation. Further resource checks will be made during installation to verify that these initial estimates are sufficient. ****************************************************************************** End of installp PREVIEW. No apply operation has actually occurred. ****************************************************************************** Continue the installation [y|n]? Type y and press Enter to start the update. The output of the updateios command is very verbose and left out of this example. 5. After a successful update, you must accept the license again: $ license -accept To check the update, run the ioslevel command: $ ioslevel 1.3.0.0 6. Reboot the Virtual I/O Server. After the Virtual I/O Server is up and running again, we need to log in to the client partitions using the first updated VIOS to resynchronize the volume group on the mirrored client partition and to change the path status on the MPIO client partition. This will update the mirror to include any disk I/O that took place during the software upgrade. In a mirrored environment, issue the lsvg command on the client partitions to check the status of your volume group: # lsvg -l rootvg rootvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT hd5 boot 1 2 2 closed/syncd N/A hd6 paging 4 8 2 open/syncd N/A hd8 jfs2log 1 2 2 open/stale N/A hd4 jfs2 1 2 2 open/syncd / hd2 jfs2 5 10 2 open/syncd /usr hd9var jfs2 1 2 2 open/stale /var Chapter 5.
