Deployment Guide

a. For cluster configurations, group hosts together so that all hosts within the group share the same storage.
● If this host is the first host in the cluster, select create a new host group, then provide a name and click Next.
● If this host is being added to a host group that exists, select Add to existing host group. Select the group from the
drop-down list, then click Next.
NOTE: The host must be mapped with the same access, port, and LUN settings to the same volumes or volume
groups as every other initiator in the host group.
b. For stand-alone hosts, select the Do not group this host option, then click Next.
7. On the Attach Volumes page, specify the name, size, and pool for each volume, and click Next.
To add a volume, click Add Row. To remove a volume, click Remove.
NOTE: Dell EMC recommends that you update the name with the hostname to better identify the volumes.
8. On the Summary page, review the host configuration settings, and click Configure Host.
If the host is successfully configured, a Success dialog box is displayed.
9. Click Yes to return to the Introduction page of the wizard, or click No to close the wizard.
Enable and configure DM Multipathing
NOTE: Safeguard and block internal server disk drives from multipathing configuration files. These steps are meant as a
basic setup to enable DM Multipathing to the storage system. It is assumed that DM Multipathing packages are installed.
1. Run the multipath –t command to list the DM Multipathing status.
2. If no configuration exists, use the command information that is listed in step 1 to copy a default template to the directory /
etc.
3. If the DM multipathing kernel driver is not loaded:
a. Run the systemctl enable multipathd command to enable the service to run automatically.
b. Run the systemctl start multipathd command to start the service.
4. Run the multipath command to load storage devices along with the configuration file.
5. Run the multipath –l command to list the ME4 Series storage devices as configured under DM Multipathing.
Create a Linux file system on the volumes
Perform the following steps to create and mount an XFS file system:
1. From the multipath –l command output, identify the device multipathing to target creating a file system.
In this example, the first time that multipathing is configured, the first device is /dev/mapper/mpatha which corresponds
to sg block devices /dev/sdb and /dev/sdd.
NOTE:
Run the lsscsi command to list all SCSI devices from the Controller/Target/Bus/LUN map. This command
also identifies block devices per controller.
2. Run the mkfs.xfs/dev/mapper/mpatha command to create an xfs type file system.
3. Run the mkdir/mnt/VolA command to create a mount point for this file system with a referenced name, such as VolA.
4. Run the mount /dev/mapper/mpatha /mnt/VolA command to mount the file system.
5. Begin using the file system as any other directory to host applications or file services.
6. Repeat steps 1-5 for other provisioned volumes from the PowerVault Manager. For example, /dev/mapper/mpathb
corresponds to sg block devices /dev/sdc and /dev/sde.
