Chapter 23 Understanding Multipathing and FailoverProcedure1 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 list3 Reload the path claiming rules from the configuration file into the VMkernel.esxcli --server=server_name storage core claimrule load4 Run the esxcli --server=server_name storage core claiming unclaim command for each path to themasked storage device.For example:esxcli --server=server_name storage core claiming unclaim -t location -A vmhba0 -C 0 -T 0 -L1495 Run the path claiming rules.esxcli --server=server_name storage core claimrule runYour host can now access the previously masked storage device.Define NMP SATP RulesThe NMP SATP claim rules specify which SATP should manage a particular storage device. Usually you donot need to modify the NMP SATP rules. If you need to do so, use the esxcli commands to add a rule to thelist of claim rules for the specified 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 youfor a user name and password. Other connection options, such as a configuration file or session file, aresupported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.PrerequisitesInstall vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started withvSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.Procedure1 To add a claim rule for a specific SATP, run theesxcli --server=server_name storage nmp satp rule add command. The command takes thefollowing options.Option-b|--boot-c|--claim-option=string-e|--description=string-d|--device=string-D|--driver=string-f|--force-h|--helpDescriptionThis is a system default rule added at boot time. Do not modify esx.conf oradd to host profile.Set the claim option string when adding a SATP claim rule.Set the claim rule description when adding a SATP claim rule.Set the device when adding SATP claim rules. Device rules are mutuallyexclusive with vendor/model and driver rules.Set the driver string when adding a SATP claim rule. Driver rules aremutually exclusive with vendor/model rules.Force claim rules to ignore validity checks and install the rule anyway.Show the help message.VMware, Inc. 233
