Procedure
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.
Define NMP SATP Rules
The NMP SATP claim rules define which SATP manages a particular storage device. Usually, you can
use the default settings for the NMP SATP rules. If you need to modify the rules, use the esxcli
commands to add a rule to the list of claim rules for the specific SATP.
You might need to create a SATP rule when you install a third-party SATP for a specific storage array.
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.
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.
