Complete the following tasks before upgrading to HMC 6 or Version 5.
Task 1. Obtain recovery media
On the Downloads page for the desired HMC Version, find the "Recovery media options" section, and then click the link for the option you prefer for obtaining the recovery media. If you choose the download method, you then need to burn the ISO images onto a DVD. You can use any method you prefer, or you can use the following Linux method:
Task 2. Back up critical data
As a safety precaution, IBM recommends that you back up critical
console data before performing either of these tasks. See your operations guide for more information on backing up the HMC.
Task 3. Verify internal modem compatibility
Follow these steps to verify internal modem compatibility.
- Determine the HMC model.
The internal modem compatibility check applies to HMC model 7310-C04 and 7310-C05. If your HMC is any other model, or does not contain an internal modem, then proceed with the upgrade. Otherwise, continue with the next step.
- Install the monkacpid efix.
IBM has identified a compatibility issue with the HMC model 7310-C04 and 7310-C05 with some internal modems. The following corrective service packages have been
created to check for the compatibility problem:
HMC Version 4: PTF MH00854
HMC Version 5: PTF MH00840
To obtain the appropriate PTF, refer to the "Download" page for your current HMC release: V4.x or V5.x.
If you have a 7310-C04 or 7310-C05, install the appropriate PTF for your current release. Next, follow the instructions included in the Readme (the "View" link for the PTF) to check for modem compatibility and, if needed, obtain a modem replacement. Do not upgrade to HMC Version 6 unless your modem has passed the compatibility check.
- Run the monkacpid command.
In a restricted shell terminal at the HMC or from a remote client over SSH, run the monkacpid command. Below is a sample output of the command which is refreshed every 4 seconds:
