Scenario 3

Scenario:

You are optimizing your vSphere environment. You are concerned about the performance of disk I/O. You want to ensure that vSphere is configured to utilize the storage in an efficient manner.

Requirements:

On a specific ESXi host, examine the currently available paths to a particular datastore.
Perform all work using the vMA and vicfg-* commands.

Environment Information:

Datastore: VMFS-01
ESXi host: host-02.lab.local
vMA: vma-01.lab.local

VDCA510 Objective: 1.3 Configure and Manage Complex Multipathing and PSA Plug-ins
VDCA550 Objective: 1.3 Troubleshoot complex storage solutions

Solution

Use Putty (or another SSH tool) to connect and log in to vma-01.lab.local as vi-admin.
Prepare to use any appropriate connection method (fastpath, --server, --vihost, and so on) to ensure the following command is performed on the ESXi host = host-02.lab.local.
Use this command to determine the device ID of the datastore: vicfg-scsidevs –m.
Use this command to list all the paths to the specified LUN: vicfg-mpath –L | grep device-ID.
