Setting up VPLEX
2. Type the following command to claim the storage volume(s) that
you will use for the logging volume:
storage-volume claim -n <storage_volume_name> -d
<storage_volume_ID>
where:
• <storage_volume_name> is an unique name you are assigning to the volume.
• <storage_volume_ID> is the ID (for example, Symm2206_2ADF, or
clar2065_LUN537) in the output from step 1 .
Note: If you want to claim multiple storage volumes, separate the volume IDs with
commas or use the command storage-volume claimingwizard , as described in the
VPLEX CLI Guide.
3. Type the following command to create an extent:
extent create -d <storage-volume_name> , <storage-volume_
name> , .....
Repeat this step for each extent you want to create on the cluster.
4. Type the following commands to create the logging volume:
cd /clusters/cluster- <Cluster_ID> /system-volumes
logging-volume create -n <name> -g <raid_geometry> -e <extent_1> ,
<extent_2> [ , <extent_3> ... <extent_n> ] -d <stripe_depth>
where:
• <name> is a name for the logging volume.
• <raid_geometry> is the RAID type: raid-0 or raid-1 .
• <extent_> identifies the name(s) of the extent(s) that make(s) up the logging
volume.
• -d <stripe_depth> is required only if <geometry> is raid-0 .
The stripe depth must be:
– Greater than zero, but no greater than the number of blocks of the smallest
element of the RAID 0 device being created
– A multiple of 4000 bytes
Note: A depth of 32 means that 128 K (32 x 4 K) is written to the first disk, the next
128 K is written to the next disk, and so on.
Example for cluster 2:
logging-volume create -n cluster_2_log_vol -g raid-0 -e ext1 , ext2
-d 32
5. From the VPlexcli prompt on management server 1, repeat steps 1
through 4 for cluster 1.
Task 26: Verify that
the clusters are fully
connected 1. From the VPlexcli prompt on management server 1, type the
following command, and verify that all directors in cluster 2 appear in the output:
ll /engines/engine-2-*/**/directors
VPlexcli-2
VPlexcli-2
VPlexcli-2
VPlexcli-1
VPlexcli-1
