Dell EqualLogic PS-M4110 Installation Guide Setting the Member RAID Policy
Setting the Member RAID Policy
The storage space in a new group member (array) is not available until you configure a RAID policy on the
member. A RAID policy consists of a RAID level and a spare disk configuration. When you select a RAID
policy, the member’s disks are automatically configured with the selected RAID level and the appropriate
number of spare disks.
If you used the Remote Setup Wizard to create a group, the RAID policy for the first member is set according to
your RAID policy selection when configuring the software, and the storage is ready to use. See
Allocating
Storage on page 49 .
If you used the Setup Utility to create or expand a group, or added the array to an existing group with the Remote
Setup Wizard, you must set the RAID policy for the group member.
Use either the Group Manager command line interface (CLI) or the Group Manager graphical user interface
(GUI) to set the RAID policy.
Note:
If you cannot launch the PS Series array Group Manager GUI interface, the group IP address may be on a
network or subnet that is different than the network or subnet where the CMC is located. In this case, you need
to set up the array management port. See
Setting up a Dedicated Management Port on page 46 . Once the
management port is set up, the Group Manager GUI is accessible only on the management network.
Using the CLI to Set the RAID Policy
To use the Group Manager CLI to set the RAID policy for a new group member:
1. Log in to the group, if you are not already logged in. (After the setup utility completes, you will still be
logged in to the group.)
Use one of the following methods to connect to the group:
–
Serial connection to a member. See Setting Up a Serial Connection to the Array on page 37 .
–
Telnet or ssh connection to the group IP address.
2. At the login prompt, enter the grpadmin account name and the password that you specified when creating the
group.
3. At the Group Manager command prompt, enter the following command, specifying raid50, raid5, raid10,
raid6, or raid6-accelerated (only available XS array models) for the
policy variable:
member select member_name raid-policy policy
For example, the following command configures member1 with RAID50:
group1> member select member1 raid-policy raid50
