Chapter 6 Capacity Expansion

Second, Reconstruct to Add Capacity
After you have installed the additional physical capacity, run HP NetRAID Config
to reconstruct the HP NetRAID logical drive to include the added capacity, as
follows:
1. Load the HP NetRAID Config utility ( megamgr.nlm module) under
NetWare.
2. The HP NetRAID Config Management menu is displayed. Choose the
Advanced menu, and press Enter.
3. In the Advanced menu, the only item is Reconstruct Logical Drive. Press
Enter to choose it.
4. The configured logical drives are displayed. Choose the one you want to
expand, and press Enter.
5. After the physical drives are rescanned, the Reconstruct screen shows the
configured logical drives and the Ready physical drives, which include the
physical drive that you installed.
6. Choose the Ready physical drive to add to the array supporting the logical
drive that you want to expand. Choose Reconstruct, and press Enter.
7. Confirm your choice. Reconstruct of the logical drive begins.
In our example, this allows you to add the drive and reconstruct the
four-drive RAID 5 array to a five-drive RAID 5 array.
Reconstruction is done in the background so there is no need to shut down
the server. When reconstruction finishes, our sample drive now has 16 GB
of available physical capacity. The original 12-GB volume VOL1 is still
intact.
The reconstruction rate is about 80 to 180 MB per minute (depending on
drive performance and system loading). Count the capacity to be
reconstructed as the number of physical drives participating in the
reconstruction multiplied by drive capacity.
Third, Make the Added Capacity Available in NetWare 5
After the logical drive has been reconstructed in HP NetRAID Config, make the
added capacity available in NetWare 5, as follows:
1. In NetWare 5, type nwconfig and press Enter.
2. The Configuration Options screen is displayed. Choose Standard Disk
Options, and press Enter.
3. Choose Scan for additional devices, and press Enter.
