17 Dell PS Series Storage: Choosing a Member RAID Policy | TR1020 | v 4.7
3 Setting the member RAID policy
When a new group is created, or a new member is added to an existing group, the RAID policy must be
selected before the space on the member is available.
Once the RAID policy is select the disks are automatically configured according to the designated RAID level,
with the appropriate number of spare disks.
Note: Starting with PS Series firmware v6.0.0, RAID 5 is not an available option in the GUI and RAID 50 is
no longer preferred for arrays with disks 1 TB or greater regardless of the firmware level. For larger than 6
TB disks RAID 10 is not a recommended practice.
To set the member RAID policy in the GUI:
1. Click Members > member_name
2. A dialog box opens, warning that RAID is not configured on the member. Click Yes to configure the
member.
3. In the General Settings dialog box, click Next.
4. In the RAID Configuration dialog box, select the RAID policy.
5. By default, the space on the member is available immediately, before the initialization completes and
the batteries are fully charged. Select the option to wait until initialization completes. Click Next.
6. Review the summary information and click Finish to initialize the member.
To set the member RAID policy in the CLI, enter the following command:
> member select member_name raid-policy policy
Specify RAID 6, RAID 10, RAID 50 (if presented) for the policy variable.
