Resolution
Please follow below procedure to add new DAC disks to mapr service.
1. Login to SAW node as administrator.
2. Run below commands in sequence.
maprcli disk add -host <host> -disks /dev/sdk,/dev/sdl,/dev/sdm
maprcli disk add -host <host> -disks /dev/sdn,/dev/sdo,/dev/sdp
maprcli disk add -host <host> -disks /dev/sdq,/dev/sdr,/dev/sds
maprcli disk add -host <host> -disks /dev/sdt,/dev/sdu,/dev/sdv
maprcli disk add -host <host> -disks /dev/sdw,/dev/sdx,/dev/sdy
Note: <host> needs to be either localhost or self IP address of SAW node.

3. Please use below commands to verify disks added successfully to mapr service.
 
/opt/mapr/server/mrconfig sp list
maprcli disk listall|grep -i Mapr

Sample output:
/opt/mapr/server/mrconfig sp list output shows new disks added to storage pools.
