In the previous chapter, you learned about storage components, such as the LUN name, identifier name, and runtime name; how to set up LUN masking in a vSphere host using esxcli
commands; and setting up the vSphere Syslog Collector to collect the ESXi host's log. During configuration and installation, the vSphere administrator may collect some information (such as the WWN of the host bus adapter of the vSphere host) and verify the path policy of the vSphere host. Executing the command is more convenient than using the vSphere client.
In this chapter, we will cover these topics:
Analyzing PSA and multipathing by esxcli
Applying VMFS volume copies resignaturing
Troubleshooting VMware snapshots and VMFS resignaturing
VMFS data store volume unmounting
Identifying and tagging SSD devices
