POWERVM - VIOS UPDATE

VIOS update:


1. create backup:
    VIO Operating System (device mappings will be backed up as well?)
    backupios -file /mnt/backup                <--this will create nim_reources.tar file (in this are an mksysb,a spot dir...)
    backupios -file /mnt/backup -mksysb        <--this will create only an mksysb

    For NIM restore these are needed on NIM server:
        -create a resource from the mksysb (smitty nim -> administration -> resources -> define...)
        -create a spot resource from the mksysb (smitty nim -> administration -> resources -> define... -> source will be the mksysb)


    Device Configurations (Logical Devices, Virtual Devices, Device Attributes):
    (On 1.3.2 did not work)
    viosbr -backup -file /mnt/vio/vios1_devicebackup        <--creates a backup
    viosbr -view -file backup_1.tar.gz                      <--view in the backup file   

    (viosbr is needed if we restore to a different server. For the same server, backupios should be enough, as it contains mappings...)
    (For restore: viosbr -restore ....)

    savevgstruct                       <--saves other vgs
    restorevgstruct                    <--resore vgs to empty disk

    Other:
    lsmap -all, lsmap -all -net, lsmap -all -npiv...
    .profile file

2. remove interim fixes:
    # oem_setup_env                     <--from the VIOS command line
    # emgr -P                           <--list installed efix's (by label)
    # emgr -r -L                        <--for each additional efix listed, run to remove


3. do the update (as padmin)
    $ mount remote_machine:directory /mnt    <--mount the remote directory onto the Virtual I/O Server
    $ updateios -commit                      <--commit previous updates, by running the updateios command
    $ updateios -accept -dev /mnt            <--for updates -install is not needed
    ($ updateios -accept -install -dev /mnt  <--this will install new filesets as well)
    $ ioslevel                               <--verify update (it should indicate:ioslevel is now V1.5.2.1-FP-11.1)
    $ shutdown -restart                      <--to load all changes, reboot the VIOS as user padmin
