Is there a maximum number of the disks which could be added to the controller ?<BR />Would I be able to allocate 2 more disks to the spareset apart from adding 3 additional disks on the raidset R1 ?<BR />Addition of the disks to the controller and raidset can be done while the system running and without disruption of any services ?<BR /><BR />My current firmware version of the controller is V27D-1<BR /><BR />Cheers Sat, 10 Jun 2006 15:34:47 GMT iman_1 2006-06-10T15:34:47Z https://community.hpe.com/t5/operating-system-openvms/disk-addition/m-p/3803700#M76819 Dear all,<BR /><BR />I would be adding a few more disks to the HSD30 controller with config as below<BR /><BR />Name Storageset Uses Used by<BR />------------------------------------------------------------------------------<BR /><BR />R1 raidset DISK100 D3<BR /> DISK110 <BR /> DISK120 <BR /> DISK200 <BR /> DISK210 <BR /> DISK220 <BR /> DISK300 <BR /> DISK310 <BR /><BR />A few queries regarding the same<BR /><BR />How many more disks can be added to the controller on the same raidset.

Unfortunately, you cannot dynamically add single disk drives to existing storage sets to expand their capacity. Some more modern HSx controllers allow a one-time concatination of storage sets of the same type, but I am afraid the HSD series do not have that feature.<BR /><BR />You only way is to:<BR />- backup all data<BR />- DELETE the unit and the RaidSet<BR />- create a new RaidSet with the ADD command<BR />- INITIALIZE the RaidSet to write new metadata<BR />- ADD the unit<BR />- restore all data<BR /><BR />I haven't heard that there is a limit on the number of disk drives in the spare set, so you should be fine, here.
