Task 26: Register Cluster 2; Task 27: Join The Clusters; Task 28: Create Logging Volumes - EMC VPLEX with GeoSynchrony 4.2 Installation And Setup Manual

Task 26: Register
cluster 2
!
Task 27: Join the
clusters
Task 28: Create
logging volumes
!
You must register the cluster with EMC in order to receive service.
From the VPlexcli prompt, type the following command, and follow
VPlexcli-2
the instructions:
configuration register-product
CAUTION
Registering this product is the only way to ensure that EMC can provide quality
support. Be sure to complete the registration and email it to EMC.
VPlexcli-2 From the VPlexcli prompt on management server 2, type the
following command, which verifies connectivity between cluster 1's directors and
cluster 2's directors, and joins the directors into a unified configuration:
configuration join-clusters
You must create a logging volume on each VPLEX Metro cluster. Each logging
volume must be large enough to contain one bit for every page of distributed storage
space (approximately 10 GB of logging volume space for every 320 TB of distributed
devices).
The logging volumes experience much I/O during and after link outages. The
recommended best practice is to stripe each logging volume across many disks for
speed, and also to have a mirror (on another fast disk), because this is important data.
CAUTION
If a logging volume does not exist, every link failure could cause a full
resynchronization of every distributed device in the system.
To create the logging volumes, you first must claim the storage volumes that will be
used, and create extents from those volumes:
1. VPlexcli-2 From the VPlexcli prompt on management server 2, type the
following commands to list the storage volumes:
cd /clusters/cluster-<Cluster_ID>/storage-elements/storage-volumes
ll
2. Type the following command to claim the storage volume(s) that
VPlexcli-2
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,
VPD43T4:710601808cc0250018f264971e83de10) 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.
