Chapter 2. IBM TotalStorage Enterprise Storage Server configuration 115

Viewing changes on the Graphical View panel

Device adapter pair number four and the connected SSA loops now look like that

shown in Figure 2-47.

Figure 2-47 Four disk groups configured

Undefining disk groups or redefining disk groups

It may be necessary to reconfigure disk groups. They can be unconfigured or

configured to another storage type. If there is a disk group configured for RAID 5,

it can be reformatted to JBOD or unconfigured. Doing this is the same process as

we did before.

First we select the disk group in the Available Storage table and then we have to

choose Undefined or non-RAID in the Disk Group Attributes field. After we get a

warning that all volumes on the selected disk group will be destroyed, we can

select the next disk group to be reconfigured. After changing the attributes of the

disk groups we perform the update.

A window pops up, informing us that the process will take a while and that we

can view the progress on the Status panel. This is with four disk groups in the

process of formatting, as illustrated in Figure 2-48.
