The HMC interface provides two methods for applying HMC corrective service, which includes HMC updates and specific fixes:
- Install from removable media.
- Install from a remote system (one of your remote systems or the Internet).
You can use either method to install update packages or specific fixes.
Note that installing an HMC update can include installing a required maintenance package. You can install the maintenance package at the same time that you install the update or, if your HMC is at the desired Release level, you can install the required maintenance as a specific fix.
