Customizing the standby BOS
You can use the multibos customization operation, with the -c flag, to update the standby BOS.
The customization operation requires an image source (-l device or directory flag) and at least one installation option (installation by bundle, installation by fix, or update_all). The customization operation performs the following steps:
- The standby BOS file systems are mounted, if not already mounted.
- If you specify an installation bundle with the -b flag, the installation bundle is installed using the geninstall utility. The installation bundle syntax should follow geninstall conventions. If you specify the -p preview flag, geninstall will perform a preview operation.
- If you specify a fix list, with the -f flag, the fix list is installed using the instfix utility. The fix list syntax should follow instfix conventions. If you specify the -p preview flag, then instfix will perform a preview operation.
- If you specify the update_all function, with the -a flag,
it is performed using the install_all_updates utility. If you specify
the -p preview flag, then install_all_updates performs a preview
operation. Note: It is possible to perform one, two, or all three of the installation options during a single customization operation.
- The standby boot image is created and written to the standby BLV using the AIX® bosboot command. You can block this step with the -N flag. You should only use the -N flag if you are an experienced administrator and have a good understanding the AIX boot process.
- If standby BOS file systems were mounted in step 1, they are unmounted.
Automatic file system expansion
The multibos -X flag auto-expansion feature allows for automatic file system expansion, if space is necessary to perform multibos-related tasks. You should run all multibos operations with this flag.
