Choose Rebuild from the Management Menu to rebuild one or more failed

Check Consistency Menu

Choose this option to verify the redundancy data in logical drives using

RAID levels 1 or 5. When you choose Check Consistency, the parameters of

the existing logical drives on the current controller appear. The logical drives

are listed by number. PERC 3 automatically corrects any differences found

in the data. Perform the following steps to run a consistency check.

1 Press the arrow keys to select the desired logical drives.

2 Press the spacebar to select or deselect a drive for the consistency

check.

3 Press <F2> to select or deselect all the logical drives.

4 Press <F10> to begin the consistency check.

A progress indicator for each selected logical drive appears.

5 When the consistency check is finished, press any key to clear the

progress display.

6 Press <Esc> to display the Management Menu.

Reconstruct Menu

You can select or deselect a logical drive to be recreated using this option.

Choose this option before you add or remove a physical drive.

Designating Drives as Hot Spares

Hot spares are physical drives that are powered up along with the RAID

drives and usually stay in a standby state. If a physical drive used in a RAID

logical drive fails, a hot spare will automatically take its place and the data

on the failed drive is reconstructed on the hot spare. Hot spares can be used

for RAID levels 1 and 5. Each PERC 3 controller supports up to eight hot

spares. See Chapter 2 "Introduction to RAID" for an explanation of hot

spares.

Perform the following steps to designate physical drives as hot spares:

1 2 ... 192 193 194 195 196 197 198 199 200 201 202 ... 253 254
