If you have already planned an outage for the upgrade, I would consider downloading the 153 ISO image from the server located in Boulder.
open a DOS window
enter 'anonymous' as the id
enter 'your e-mail address' as the password
Be sure to check the prereq's before upgrading:
- ensure that the network connections between the HMC and server are good (connected) before you update the code
- ensure power microcode is at the 155 level, minimum
- ensure the HMC is upgraded to the latest efix of MH00454
- apply code
- verify after the update
Again, this only applies to the p590/p595 models.
