Procedure
1 Delete the MASK_PATH claim rule.
esxcli storage core claimrule remove -r rule#
2 Verify that the claim rule was deleted correctly.
esxcli storage core claimrule list
3 Reload the path claiming rules from the configuration file into the VMkernel.
esxcli storage core claimrule load
4 Run the esxcli storage core claiming unclaim command for each path to the masked storage
device.
For example:
esxcli storage core claiming unclaim -t location -A vmhba0 -C 0 -T 0 -L 149
5 Run the path claiming rules.
esxcli storage core claimrule run
Your host can now access the previously masked storage device.
Define NMP SATP Rules
The NMP SATP claim rules define which SATP manages a storage device. Usually, you can use the
default SATPs provided for storage devices. If default settings are not sufficient, use the esxcli
commands to change the SATP for a specific device.
You might need to create an SATP rule when you install a third-party SATP for a specific storage array.
Prerequisites
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.
Procedure
1 To add a claim rule for a specific SATP, run the esxcli storage nmp satp rule add command.

-c|--claim-option=string
