Chapter 2 HP NetRAID Assistant

Changing Logical Drives Currently in Use

You can make several kinds of changes to logical drives that are currently in use.

You can:

• Change the RAID level.

• Remove a physical drive.

• Add a physical drive. See Chapter 6, "Capacity Expansion," in this guide

for complete instructions.

All such changes to existing logical drives require reconstructing the data.

Reconstruction is the process of reorganizing the data to correspond to a change

in the HP NetRAID system. Reconstruction occurs in the background, so the

HP NetServer and the affected logical drive remain available throughout the

reconstruction process.

NOTE Once started, the reconstruction process cannot be stopped.

The Power Fail Safeguard feature protects logical drives against data loss during

the reconstruction process should a power failure occur. For complete

information, see "Power Fail Safeguard Feature" in Chapter 5 in this guide.

Changing the RAID Level of a Logical Drive

To make RAID level changes, refer to the valid RAID level changes listed in the

following table when altering a logical drive.

NOTE You cannot change the RAID level of any logical drive that

spans arrays (RAID levels 10, 30, or 50).

1 2 ... 41 42 43 44 45 46 47 48 49 50 51 ... 160 161
