Performing the Live Update operation by using the geninstall command

After the /var/adm/ras/liveupdate/lvupdate.data file is created, you can use the geninstall command to initiate a AIX® Live Update operation.

Use the following steps to start the Live Update operation by using the geninstall command:

If the logical partition (LPAR) is managed by an HMC, authenticate HMC.
```
# hmcauth -u hscroot -a hmc_name
```
If the LPAR is managed by PowerVC, authenticate PowerVC.
```
# pvcauth -u root -a powervc_host
```

Run the Live Update operation in preview mode.

# geninstall -k -p -d /tmp IZ12345.140806.epkg.Z

Run the Live Update operation for the specified type of update.
- To install an interim fix, run the following command:
```
# geninstall -k -d /tmp IZ12345.140806.epkg.Z
```
- To install the updates to two filesets and to install an interim fix, run the following command:
```
# geninstall -k -d /tmp bos.mp64 bos.rte.libc IZ12345.140806.epkg.Z
```
- To install all the updates and interim fixes that are available in the /tmp/source directory, run the following command:
```
# geninstall -k -d /tmp/source all
```
  Note: If the installation of the updates fails, the Live Update operation stops without installing the interim fixes.
- To install all the updates, but not interim fixes, that are located in the /tmp/updates directory, run the following command:
```
geninstall -k -d /tmp/updates update_all 
```
Note: You can install any updates and interim fixes by using your preferred methods, and then perform a Live Update operation instead of restarting the system by running the following command:
```
# geninstall -k
```
