Creating a Storage Pool Using mrconfig
About this task
CAUTION
The mrconfig
command must be run under the
supervision of HPE support. To create a storage pool using mrconfig:
Procedure
-
Assume the disks
/dev/sdb
,/dev/sdc
, and/dev/sdd
are available; initialize them withmrconfig disk init
:/opt/mapr/server/mrconfig disk init /dev/sdb /opt/mapr/server/mrconfig disk init /dev/sdc /opt/mapr/server/mrconfig disk init /dev/sdd
-
Create a disk group with
mrconfig dg create
:/opt/mapr/server/mrconfig dg create raid0 -d 128 /dev/sdb /dev/sdc /dev/sdd
-
Create a concatenated disk group with
mrconfig dg create concat
by specifying the primary drive./opt/mapr/server/mrconfig dg create concat /dev/sdb
-
At this point, you can use
mrconfig dg list
to see the layout of the disk group, and which disk is the primary disk. The primary disk can be used in other commands to refer to the disk group as a whole. Example:/opt/mapr/server/mrconfig dg list
-
From the disk group, create a storage pool with
mrconfig sp make
:/opt/mapr/server/mrconfig sp make /dev/sdb
