3: Using TPM

Figure 3-14

LUN is Defined

The right-hand side of the table shows how the LUN is physically arranged on each
disk drive.

6. To continue building LUNs that incorporate drives in other packs, click

Select

Pack(s)

 and repeat the process of defining LUNs and their corresponding RAID

levels and usable MB.

Figure 3-15 (6.14 firmware) or Figure 3-16 (7.01 and later firmware) shows how the
screen appears after using all the drive packs to define three separate LUNS.
