vSphere Storage - ESXi 5.1 - Documentation - VMware

vSphere Storage
Procedure
u To list VMware SATPs, run the following command:
esxcli --server=server_name storage nmp satp list
For each SATP, the output displays information that shows the type of storage array or system this SATP
supports and the default PSP for any LUNs using this SATP. Placeholder (plugin not loaded) in the
Description column indicates that the SATP is not loaded.
Display NMP Storage Devices
Use the esxcli command to list all storage devices controlled by the VMware NMP and display SATP and PSP
information associated with each device.
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.
Procedure
u To list all storage devices, run the following command:
esxcli --server=server_name storage nmp device list
Use the --device | -d=device_ID option to filter the output of this command to show a single device.
Add Multipathing Claim Rules
Use the esxcli commands to add a new multipathing PSA claim rule to the set of claim rules on the system.
For the new claim rule to be active, you first define the rule and then load it into your system.
You add a new PSA claim rule when, for example, you load a new multipathing plug-in (MPP) and need to
define which paths this module should claim. You may need to create a claim rule if you add new paths and
want an existing MPP to claim them.
CAUTION When creating new claim rules, be careful to avoid a situation where different physical paths to the
same LUN are claimed by different MPPs. Unless one of the MPPs is the MASK_PATH MPP, this configuration
will cause performance problems.
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.
