Users Guide

RAID5 is no longer considered a best practice for data protection of business critical data on Dell EqualLogic arrays, but it can be

configured using the Group Manager CLI.

For more information about RAID policies on PS Series systems, see the Dell Technical Report, PS Series Storage Arrays: Choosing a

Member RAID Policy, at http://en.community.dell.com/dell-groups/dtcmedia/m/mediagallery/19861480.

Example: Initializing a PS Series Array

The following example includes the serial number (--sn), member name (--mn), member IP address ( --mip), subnet (--msub),

member gateway (--mgwy), create group ( --cg), group name (--gn), group IP address (--gip), and RAID policy (--raid)

parameters. By omitting the membership (--membership) parameter from the command line, you are prompted to enter the password

as the command executes. Using this method hides the password for added security.

# rswcli --initialize --sn VM000c2939fd8b3 --mn farm31 --mip 192.x.x.xx

--msub 255.255.0.0 --mgwy 10.xxx.x.x --cg --gn farm31-grp

--gip 192.x.x.xy --raid 50

Managing Access to a PS Series Group

The RSWCLI provides several commands for managing group access. With these commands, you can list the available groups, add access

to a group, modify group parameters, and remove group access. PS Series arrays initialized using RSWCLI are automatically added to the

list of accessible groups.

Adding group access registers the group with iscsiadm and adds it to the discovery portal list. Similarly, removing a group removes the

group IP from the list of discovered portals. If a group has been manually discovered with iscsiadm, you do not need to add group access

with the rswcli --add-group-access command.

This section provides the following information for managing group access:

• Adding Access to a Group

• Listing Accessible Groups

• Modifying Access to a Group

• Removing Host Access to a Group

• Configuring Multipath I/O

Adding Access to a Group

Use the rswcli --add-group-access (or rswcli -a) command to configure host access to a PS Series group. The --group-

name and --group-ip command parameters are required and must not be in use by any other group.

rswcli --add-group-access Command Syntax

The command syntax is as follows:

rswcli --add-group-access | -a

--group-name group-name | --gn

--group-ip IP_address | --gip
