When you need the host to access the masked storage device, unmask the paths to the device.

In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.

Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting , run esxcli commands in the ESXi Shell.

1

Delete the MASK_PATH claim rule.

esxcli --server=server_name storage core claimrule remove -r rule#

2

Verify that the claim rule was deleted correctly.

esxcli --server=server_name storage core claimrule list

3

Reload the path claiming rules from the configuration file into the VMkernel.

esxcli --server=server_name storage core claimrule load

4

Run the esxcli --server=server_name storage core claiming unclaim command for each path to the masked storage device.

For example:

esxcli --server=server_name storage core claiming unclaim -t location -A vmhba0 -C 0 -T 0 -L 149

5

Run the path claiming rules.

esxcli --server=server_name storage core claimrule run

Your host can now access the previously masked storage device.
