Options Description
--type <type>
-t <type>
Type of matching to use for the operation. Valid values are vendor, location, driver,
and transport.
--vendor
-V
Vendor of the paths to use. Valid only if --type is vendor.
Valid values are values of the vendor string from the SCSI inquiry string. Run vicfg-
scsidevs <conn_options> -l on each device to see vendor string values.
--wwnn
World-Wide Node Number for the target to use in this operation.
--wwpn
World-Wide Port Number for the target to use in this operation.
--xcopy-max-transfer-
size
-m
Maximum data transfer size when using XCOPY. Valid only if --xcopy-use-array-
values is specied.
--xcopy-use-array-values
-a
Use the array reported values to construct the XCOPY command to be sent to the storage
array. This applies to VAAI claim rules only.
--xcopy-use-multi-segs
-s
Use multiple segments when issuing an XCOPY request. Valid only if --xcopy-use-
array-values is specied.
Claim rules are numbered as follows.
n
Rules 0–100 are reserved for internal use by VMware.
n
Rules 101–65435 are available for general use. Any third-party multipathing plug-ins installed on your
system use claim rules in this range. By default, the PSA claim rule 101 masks Dell array pseudo
devices. Do not remove this rule, unless you want to unmask these devices.
n
Rules 65436–65535 are reserved for internal use by VMware.
When claiming a path, the PSA runs through the rules starting from the lowest number and determines is a
path matches the claim rule specication. If the PSA nds a match, it gives the path to the corresponding
plug-in. This is worth noticing because a given path might match several claim rules.
The following examples illustrate adding claim rules. Specify one of the options listed in “Connection
Options for vCLI Host Management Commands,” on page 19 in place of <conn_options>.
n
Add rule 321, which claims the path on adapter vmhba0, channel 0, target 0, LUN 0 for the NMP.
esxcli <conn_options> storage core claimrule add -r 321 -t location -A vmhba0 -C 0 -T 0 -L 0
-P NMP
n
Add rule 429, which claims all paths provided by an adapter with the mptscsi driver for the MASK_PATH
plug-in.
esxcli <conn_options> storage core claimrule add -r 429 -t driver -D mptscsi -P MASK_PATH
n
Add rule 914, which claims all paths with vendor string VMWARE and model string Virtual for the NMP.
esxcli <conn_options> storage core claimrule add -r 914 -t vendor -V VMWARE -M Virtual -P NMP
n
Add rule 1015, which claims all paths provided by FC adapters for the NMP.
esxcli <conn_options> storage core claimrule add -r 1015 -t transport -R fc -P NMP
Removing Claim Rules
The esxcli storage core claimrule remove command removes a claim rule from the set of claim rules on
the system.

unless you want to unmask these devices.
