please tell me the right steps for HBA replacing in HACMPed environment. ESS + sdd.
Lets say, fcs0 is failed. When I stop hacmp services on affected node are these steps enough and ok?
1. rmdev -dl fcs0 -R
2. shutdown node
3. replace adapter in box (it is p55A)
4. power on
5. -- I expect new fcs0 devices are configured, right?
I there anything else to be done?
Should vpath devices be offline on all cluster nodes or I can keep hacmp services / resource group running on backup node?
Will reservation kept on LUNs on backup node have impact during configuring new adapter on the node were it will be replaced? Will cfgmgr configure vpath/paths properly on affected node when LUNs are reserved on backup node?
