Dell PowerVault ME4 Series Storage System CLI Guide

General rules for specifying commands

Command names and parameter names are not case sensitive.

Parameters enclosed in square brackets ([ ]) are optional. Do not type the bracket characters.

Parameter values separated by ’|’ characters are options. Enter only one of the values. Unless specified otherwise, enumerated values are not case sensitive.

Unless otherwise specified, a parameter value can include spaces and printable UTF-8 characters except: " , < > \

A parameter value that includes a space must be enclosed in double quotes. Unless specified otherwise, if you include leading or trailing spaces with a value (such as a name) in double quotes, those spaces are treated as part of the value.

Parameters can be entered in any order. However, for a parameter with no keyword, if you want to specify a value that is partially or entirely the same as the keyword of an optional parameter, you must specify the optional parameter before the value. For example, to create a user named base you must specify the optional base parameter before the name base: create user base 2 base

Specifying drawers

In an enclosure with drawers:

• Disk drawers are specified by enclosure ID and drawer number. Enclosure IDs increment from 0. Drawer IDs increment from 0 in each enclosure. Example: 2.1
• Disks are specified without the drawer number, as described below.

Specifying disks

Disks are specified by enclosure ID and slot number. Enclosure IDs increment from 0. Disk IDs increment from 0 in each enclosure. You can specify:

• A disk. Example: 1.4
• A hyphenated range of disks. Example: 1.4-7
• A comma-separated list of individual disks, ranges, or both (with no spaces). Example: 1.4,1.6-9
• A RAID 10 or 50 disk group with disks in subgroups separated by colons (with no spaces). RAID-10 example:1.1-2:1.3-4:1.7,1.10

Specifying disk groups

You can specify:

• A disk group by its name or serial number. A unique serial number is automatically assigned when a disk group is created, and does not change for the life of the disk group.
• A list of disk-group names or serial numbers separated by commas (with no spaces). Not all commands support lists. Example: dg1,"Disk group 1"

Specifying pools

For virtual storage, you can specify:

• A pool by its name or serial number.
• A list of pool names or serial numbers separated by commas (with no spaces). Not all commands support lists. Example: A,B

Specifying volumes

You can specify:

• A volume by its name or serial number. A unique serial number is automatically assigned when a volume is created, and does not change for the life of the volume.
• A list of volume names or serial numbers separated by commas (with no spaces). Not all commands support lists. List example: vd1_v1,"Vol #1".

Specifying volume groups

For virtual storage, you can specify:

• A volume group by its name in the format volume-group.*, where * represents all volumes in the group. Example: TestVolumes.*

Specifying ports

Controller module host ports are specified by port number only (to use the same port in both controllers) or by controller ID and port number (to specify a port in one controller).

In a 2U12 or 2U24 enclosure, the top controller module ID is A and the bottom controller module ID is B. In a 5U84 enclosure, the left controller module ID is A and the right controller module ID is B. Controller module IDs are not case sensitive.

Port IDs increment from 0 in each controller module.

You can specify:

• A port ID in both controllers. Example: 1
• A port ID in one controller. Example: A1
• A hyphenated range of IDs. Do not mix controller IDs in a range. Example: b1-b2 or 1-2
• A comma-separated list of IDs, ranges, or both (with no spaces). Example: A1,b1-b2 or A1,2

Specifying initiators and hosts

You can specify:

• An FC initiator by its nickname or 16-hex-digit WWPN.
• A SAS initiator by its nickname or 16-hex-digit WWPN.
• An iSCSI initiator by its nickname or node name (typically the IQN).
• A host by name in the format host-name.*, where * represents all initiators in the host. Example: Mail_Server.*

Specifying host groups

For virtual storage, you can specify:

• A host group by name in the format host-group.*.*, where the first * represents all hosts in the group and the second * represents all initiators in those hosts. Example: TestLab.*.*

Specifying fan modules

In a 5U84 enclosure:

• Fan modules are specified by enclosure ID and module number.
• Enclosure IDs increment from 0.
• Module IDs increment from 0 in each enclosure.

Example: 1.1

User password rules

• The value is case sensitive.
• The value can have 8–32 characters.
• The value can include printable UTF-8 characters except a space or: " ' , < > \
• A value that includes only printable ASCII characters must include at least one uppercase character, one lowercase character, one numeric character, and one non-alphanumeric character. This rule does not apply if the password contains UTF-8 characters that are outside the range of printable ASCII characters.
