I wanted to know do we need to do anything from host side to get this change reflected  thanks,  make sure new paths are visible on the host and are being managed by PowerPath. Unmask "old" paths and run "powermt check" to remove dead paths. If all looks good proceed with write disabling that device on old FAs and unmapping it form old FAs.
Hi All,  As a part of performance optimization,I have to use replace one pair FA with new one.Currently I have provided 4 paths(4D/0,4D/1,13D/0,13D/1) for a server currently.I am replacing 4D/1,13D/1 with new pair 7A/0,10A/0.  I have mapped the devices to the new pair.I wanted to know what is the command to unmap the devices ONLY from 4D/1 and 13D/1.If I have to unmap the devices,either I have to make WD or NR the device which will affect host access.  so can somebody tell me what is the command to unmap the device only from single pair of FA.  ?  and do we need to do anything from host side before removing the current path ?
need to know symcli command unmap devices ONLY from a single FA
