<strong>vSphere</strong> <strong>Storage</strong><br />
Procedure<br />
u To list <strong>VMware</strong> SATPs, run the following command:<br />
esxcli --server=server_name storage nmp satp list<br />
For each SATP, the output displays information that shows the type of storage array or system this SATP<br />
supports and the default PSP for any LUNs using this SATP. Placeholder (plugin not loaded) in the<br />
Description column indicates that the SATP is not loaded.<br />
Display NMP <strong>Storage</strong> Devices<br />
Use the esxcli command to list all storage devices controlled by the <strong>VMware</strong> NMP and display SATP and PSP<br />
information associated with each device.<br />
In the procedure, --server=server_name specifies the target server. The specified target server prompts you<br />
for a user name and password. Other connection options, such as a configuration file or session file, are<br />
supported. For a list of connection options, see Getting Started with <strong>vSphere</strong> Command-Line Interfaces.<br />
Prerequisites<br />
Install vCLI or deploy the <strong>vSphere</strong> Management Assistant (vMA) virtual machine. See Getting Started with<br />
<strong>vSphere</strong> Command-Line Interfaces. For troubleshooting , run esxcli commands in the <strong>ESXi</strong> Shell.<br />
Procedure<br />
u To list all storage devices, run the following command:<br />
esxcli --server=server_name storage nmp device list<br />
Use the --device | -d=device_ID option to filter the output of this command to show a single device.<br />
Add Multipathing Claim Rules<br />
Use the esxcli commands to add a new multipathing PSA claim rule to the set of claim rules on the system.<br />
For the new claim rule to be active, you first define the rule and then load it into your system.<br />
You add a new PSA claim rule when, for example, you load a new multipathing plug-in (MPP) and need to<br />
define which paths this module should claim. You may need to create a claim rule if you add new paths and<br />
want an existing MPP to claim them.<br />
CAUTION When creating new claim rules, be careful to avoid a situation where different physical paths to the<br />
same LUN are claimed by different MPPs. Unless one of the MPPs is the MASK_PATH MPP, this configuration<br />
will cause performance problems.<br />
In the procedure, --server=server_name specifies the target server. The specified target server prompts you<br />
for a user name and password. Other connection options, such as a configuration file or session file, are<br />
