Hi,
Are your frames visible for 1 or 2 HMCs? We have dual HMC setup, and sometimes RMC seems to be active only via 1 HMC...and if that is not your primary HMC from PowerVC point of view ...it will lead into situation U described.
In case U have just one HMC...there might be some temporary connection issue between PowerVC & HMC; 1st thing I'd try is restarting PowerVC services.
And please check also Configuration > Fibre Channel Port Configuration that U have free NPIV ports available in your VIOSes
Br,

Subject: Unable to attach Volume to one Frame
Hi,
We are running PowerVC Version: 1.4.4.2 and on one of the frame having issues adding volume to a VM (on other frames I can add volumes to the VM's).
Below is the error. VIOS from that frame show no RMC connection, HMC is showing RMC connection active. Attached is the screen shot.
volume 8b7ac631-3ca6-4e16-9b73-3b7b5a60ae8c could not be attached to virtual machine lpar10164.
