Hi, since a whiule SRR was enhanced that also the mkauthkeys SSH authentication can be used to perform the operation between two different HMCs.So source System in managed by HMC1 and target System is managed by HMC2.There is some Info about that in this Document:https://community.ibm.com/HigherLogic/System/DownloadDocumentFile.ashx?DocumentFileKey=7c7b05d4-0342-6338-537e-aaaf5674cea4So just like for LPM with two different HMCs, the rrstartlpar command can be used. Example:
mkauthkeys –-ip <target hmc ip/host name> -u <target hmc user name> --passwd <password>rrstartlpar –o validate –m <source system> -t <target system> -p <partition name> | --id <partition id> --ip <target hmc ip/host name> [-u target hmc user name]
As usual:As long as the LPM validation is successfull, the SRR validation / operation should also be successfull.When the Source System / LPAR is still up and running SRR validation will usually provide HSCL messages with Info ,that Validation could not be fully performed, because the LPAR / System is still up and running but that is only informational.
When the Target System can not provide the exact same Networks / SAN connections LPM / SRR might fail. Some override flags might be used to still make the operation successfull, but the LPAR might not be able to access the targets it should acces. SRR is not a HA solution !!
Hope that helps.GreetingsMarc-Eric
