Installing the auxiliary write cache
Follow these step-by-step instructions to install the auxiliary write cache.
Note: Disk arrays can be previously configured or new arrays
can be created after the auxiliary cache environment configuration
is set up.
- Ensure that both the storage I/O adapter and AWC adapter are installed in the same partition and in the same enclosure.
- Update to the latest adapter microcode from the code download web site, and to the required levels of both the AIX® version and the AIX driver package for your specific adapters. See AIX software requirements for the required code levels, and also refer to the installation information for the adapter.
- Power on the system or partition and verify the function
of adapters and disk arrays. See Viewing the disk array configuration.
