AIX clone (링크)

Because the alternate disk installation process involves cloning an existing rootvg to a target alternate disk, the target alternate disk must not be already assigned to a volume group.

For information about alternate disk installation, see Installing to an alternate disk. Also, refer to thealt_disk_copy man page.

Step 1. Prepare for the alternate disk installation

1. Check the status of physical disks on your system. Type:

   # lspv

   Output similar to the following displays:

   hdisk0         0009710fa9c79877    rootvg   	active
   hdisk1         0009710f0b90db93    None

   We can use hdisk1 as our alternate disk because no volume group is assigned to this physical disk.

2. Check to see if the alt_disk_copy fileset has been installed by running the following:

   # lslpp -L bos.alt_disk_copy.rte

   Output similar to the following displays if the alt_disk_copy fileset is not installed:

   lslpp: 0504-132  Fileset bos.alt_disk_copy.rte not installed.

3. Using volume 1 of the AIX installation media, install the alt_disk_copy fileset by running the following:

   # geninstall -d/dev/cd0 bos.alt_disk_copy.rte

   Output similar to the following displays:

   +-----------------------------------------------------------------------------+
                                   Summaries:
   +-----------------------------------------------------------------------------+
   
   Installation Summary
   --------------------
   Name                        Level           Part        Event       Result
   -------------------------------------------------------------------------------
   bos.alt_disk_copy.rte    5.3.0.0         USR         APPLY       SUCCESS

4. Create a user-defined bundle called /usr/sys/inst.data/user_bundles/MyBundle.bnd that contains the following filesets:

   I:bos.content_list
   I:bos.games

   For more information on how to create a user-defined software bundle, refer to Creating and installing a software bundle.

5. Create the /home/scripts directory:

   mkdir /home/scripts

6. Create a user-defined customization script called AddUsers.sh in the /home/scripts directory:

   touch /home/scripts/AddUsers.sh
   chmod 755 /home/scripts/AddUsers.sh

7. Edit /home/scripts/AddUsers.sh to contain the following lines:

   mkuser johndoe
   touch /home/johndoe/abc.txt
   touch /home/johndoe/xyz.txt

Step 2. Perform the alternate disk installation and customization

1. To clone the rootvg to an alternate disk, type the following at the command line to open the SMIT menu :

   # smit alt_clone

2. Select hdisk1 in the Target Disk to Install field.
3. Select the MyBundle bundle in the Bundle to Install field.
4. Insert volume one of the installation media.
5. Type /dev/cd0 in the Directory or Device with images field.
6. Type /home/scripts/AddUsers.sh in the Customization script field.
7. Press Enter to start the alternate disk installation.
8. Check that the alternate disk was created, by running the following:

   # lspv

   Output similar to the following displays: 

   hdisk0         0009710fa9c79877    rootvg
   hdisk1         0009710f0b90db93    altinst_rootvg

Step 3. Boot from the alternate disk

1. By default, the alternate-disk-installation process changes the boot list to the alternate disk. To check this run the following:

   # bootlist -m normal -o

   Output similar to the following displays:

   hdisk1

2. Reboot the system. Type:

   # shutdown -r

   The system boots from the boot image on the alternate disk (hdisk1).

Step 4. Verify the operation

1. When the system reboots, it will be running off the alternate disk. To check this, type the following:

   # lspv

   Output similar to the following displays:

   hdisk0         0009710fa9c79877    old_rootvg
   hdisk1         0009710f0b90db93    rootvg

2. Verify that the customization script ran correctly, by typing the following:

   # find /home/johndoe -print

   Output similar to the following displays:

   /home/johndoe
   /home/johndoe/.profile
   /home/johndoe/abc.txt
   /home/johndoe/xyz.txt

3. Verify that the contents of your software bundle was installed, by typing the following:

   # lslpp -Lb MyBundle

   Output similar to the following displays:

     Fileset                      Level  State  Description
     ----------------------------------------------------------------------------
     bos.content_list           5.3.0.0    C    AIX Release Content List
