Administrator Guide

• Enable the management port, if needed (see Congure a Management Network)
• Select the RAID policy (see Set the RAID Policy and Pool for a New Member)
After you complete these tasks, you can congure the new member either through the CLI or through the GUI. To congure the
member through the GUI:
1. Click Group, expand Members, and select the uncongured member.
2. In the Warning dialog box, click Yes or No.
Clicking Yes opens the Congure member dialog box, in which you select the RAID policy and specify other settings for the
member as needed. Click the question mark (?) to see more information about these settings.
Clicking No closes the Warning dialog box. When you are ready to congure the RAID policy, you can click the Congure
member link In the Activities panel to open the dialog box.
NOTE: Before updating a member, verify that it has a default gateway. If it does not, you will receive the following update
error: FTP:Error:Unknown. If you receive this error, add the default gateway and then you can update the member
from the GUI.
Set the RAID Policy and Pool for a New Member
After you add a member to a PS Series group, you must set the RAID policy for the member and choose the storage pool. The
storage in the member is available after you set the RAID policy.
Prerequisites
• Review the best practices about setting member RAID policies. For more information about RAID policies on PS Series systems,
review the Dell Technical Report entitled PS Series Storage Arrays: Choosing a Member RAID Policy, which you can download
from the following location:
http://en.community.dell.com/dell-groups/dtcmedia/m/mediagallery/19861480
• If you used the Remote Setup Wizard to create a group and add the rst member to the group, you already set the RAID policy
for the member, and the group automatically assigned the member to the default pool. See the Installation and Setup Guide for
your array.
• Member storage space is available immediately after you have set a RAID policy, although performance is not optimal until the
system nishes verifying the member’s new RAID conguration.
Convert a RAID Policy
You congure a RAID policy when you add a member to a group. In most cases, you can convert the RAID policy at a later time.
Prerequisites
• Make sure that you can change the current RAID policy to a dierent one, and that you understand the conversion options.
• To convert to a no-spare-drives RAID policy, you must use the Group Manager CLI.
• While the RAID policy is changing, the member’s RAID status is expanding.
• The values in the Member Capacity table are automatically updated, based on the RAID policy that you select.
• To ensure that member space is not available until the RAID verication completes, select Wait until the member storage
initialization completes, if this option is not selected already.
• Member performance might be temporarily degraded while the RAID policy conversion is taking place.
Procedure
1. Click Group.
2. Expand Members and then select the member name.
3. Click Modify RAID conguration to open the Modify RAID Conguration dialog box.
4. Select the new RAID policy.
