Enhancement for diagrmc command for PEP testing

To test communication between HMC before setting up a POWER Enterprise Pool between multiple HMC, the command diagrmc is used from one HMC.
The problem is: Only RMC connection is tested nothing about ssh (port 22) by default.
But "The ssh session is only used to establish a Resource Monitoring and Control (RMC) session between the HMCs." testting the communication with diagrmc is not enough.

    An informational note is added to diagrmc o/p when used with --mcip option to indicate that initial connection is done via ssh.

    We are planning to add a message to the diagrmc o/p indicating ssh is needed to setup the rmc connection when validating with a mcip.

    Even though diagrmc doesn't check for ssh connectivity between HMCs, mkcodpool or chcodpool commands does take username/password as input for ssh connectivity validation and existing mkauthkeys command can also be used to test the ssh connectivity between HMCs. So we feel that the options are already there. Can you please let us know if anything else is missing?

    Absolutely : diagrmc doesn't check for ssh connectivity between the HMC's
    so testing with only diagrmc command does only a partial test.

    Hi,

    The hmc commands mkcodpool and chcodpool take the username/password as input when you are creating the Power Enterprise Pool or modifying to add new HMC's to the pool and its used for SSH one time and is not persisted in the HMC. Is the concern here that diagrmc doesn't check for ssh connectivity between the HMC's? Can't it be directly tested by doing a ssh from one hmc to another ?

    Thanks.
