ServeRAID logical drive migration for Servers and IntelliStation.
This document contains general information on performing a ServeRAID Logical Drive Migration using the ServeRAID Manager utility program for all supported Microsoft Windows NT and Novell NetWare servers.
- Ensure that a full tape backup of data has been done.
- Click here to download and install the latest IBM Hard Drive Update program.
- Click here to download and install latest BIOS and firmware.
- Click here to download and install the latest ServeRAID drivers
- Uninstall any older ServeRAID Administration & Monitoring Utilities.
- Click here to download and install the latest IBM ServeRAID Manager program.
- Start the ServeRAID Manager program.
- Select the magnifying scope icon to scan for new ready drives
- Click Manager Systems and then click Controller 1, Arrays, then Array A (xxxxMB).
- Right-click Array A (xxxxMB) and click Properties. Record the following:
Array Size in MB XXXXX
Free Space in MB XXXXX
Number of Logical Drives X
Number of Physical Drives X
Note: This is very important so that you can make comparisons once the LDM is completed.
- Click Array A (xxxxMB), Logical Drives In Array, then click Logical Drive 1. Under the Description of Value section to the right, record the following for each logical drive:
Data Space in MB: XXXXX
Parity Space in MB: XXXXX
- Click Array A (xxxxMB), click Actions, and select Logical Drive Migration.
Important: Please read and understand this section.
- Double-click the number of (RDY) drives and click Next.
- Select one of the following options:
- Increasing free space - Using this feature you can add one, two, or three physical hard drives to an existing array so you can create another logical drive in the array.
- Increase logical drive space - Using this feature you can add one, two, or three physical hard drives to an existing array so you can expand the size of the logical drives in the array.
To add physical hard drives to an existing array to create another logical drive in the array complete the following steps:
Example using 4x9.1GB drives, with 2x 750MB logical drives created on the same array | Logical Drive | Size | New size | Level | New level |
| 1 | 750MB | 750MB | 5 | 5 |
| 2 | 750MB | 750MB | 5 | 5 |
| Free space | 23784KB | 32712KB | 0 | 0 |
Click Apply, and you will now see a 3rd Logical Drive appear as a GRAY drive indicator, which states the following: Logical Drive 8 (750MB)
- Right-click Array A (xxxxMB) and click Properties. Record the following changes:
Array Size in MB: 26034 <- Size of (3) 9.1GB drives
Free Space in MB 23784
Number of Logical Drives 2
Number of Physical Drives 3
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 32462 <- Notice the increase of size from above
Number of Logical Drives 3 <- Added the virtual logical drive
Number of Physical Drives 4 <- Total amount of drives in array
After each LDM completes, a synchronization of the logical drive is performed.
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 32587 <- Notice the increase of size from above
Number of Logical Drives 3 <- Added the virtual logical drive
Number of Physical Drives 4 <- Total amount of drives in array
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 32712 <- Notice the increase of size from above
Number of Logical Drives 2 <- Total number of logical drives
Number of Physical Drives 4 <- Total amount of drives in array
Note: After the migration has completed for Increase the free space by XXXXMB in array X option, you can go to ServeRAID Manager, under Managed Systems, select the Logical Drives In Array A selection, go to the Actions menu, and select Create Logical Drive In Array A.
Each logical drive will represents a disk in Windows NT Disk Administrator.
- Now minimize the ServeRAID Manager program and open Windows NT Disk Administrator. Below is an example of what you should expect to see:
Disk 0
750MB 
Note: That there is no change in partition size.
Disk 1
750MB 
Note: That there is no change in partition size.
Disk 2
XXXMB 
Note: You can change the RAID levels when no (RDY) drives are available, by selecting Array A (xxxxMB), and go to the Actions menu, select Change Raid Level from X to X
To add physical hard drives to an existing array expand the size of the logical drives in the array complete the following steps:
Example using 4x 9.1GB drives, with 2x 750MB logical drives created on the same array | Logical drive | Size | New size | Level | New level |
| 1 | 750MB | 1125MB | 5 | 5 |
| 2 | 750MB | 1125MB | 5 | 5 |
| Free space | 23784KB | 32712KB | None | None |
- Click Apply, and you will now see a 3rd Logical Drive appear as a GRAY drive indicator, which states the following: Logical Drive 8 (1125MB)
Right-click Array A (xxxxMB) and click Properties.
Notice the following changes:
Array Size in MB: 26034 <- Size of (3) 9.1GB drives
Free Space in MB: 23784
Number of Logical Drives 2
Number of Physical Drives 3
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 32462 <- Notice the increase of size from above
Number of Logical Drives 3 <- Added the virtual logical drive
Number of Physical Drives 4 <- Total amount of drives in array
After each LDM completes, a synchronization of the logical drive is performed.
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 32087 <- Notice the decrease of size from above
Number of Logical Drives 3 <- Added the virtual logical drive
Number of Physical Drives 4 <- Total amount of drives in array
Array Size in MB: 34712 <- New size of (4) 9.1GB drives
Free Space in MB: 31712 <- Notice the decrease of size from above
Number of Logical Drives 2 <- Total number of logical drives
Number of Physical Drives 4 <- Total amount of drives in array
- Now that the LDM has completed, exit the ServeRAID Manager program, shut down NT and reboot.
- Start the Windows NT Disk Administrator program, and select YES to write signatures when asked. See the following examples
Disk 0
1124MB 
Note: That there is no change in partition size, but an increase in the disk size.
Disk 1
1124MB 
Note: That there is no change in partition size, but an increase in the disk size.
Tip: You can only make the free space at the end of the C: partition, a new partition. You cannot make this a full partition. But you can totally delete only your 750MB D: partition, and merge the new free space to make full 1124MB partition, by performing the following:
- Backup your data on any partition other than C:\ partition.
- Right-click D:\ and select Delete, you should see the following:
Disk 1
1124MB 
- Right-click the free space and select Delete. You should see the following:
Disk 1
1124MB 
- Right-click the new free space
- SelectCreate/Commit Changes Now,
- Select YES to create partition anyway
- Select Commit Changes Now
- Right-click the new free space again, you now have the option to Format.
You should now have one complete partition, ready to be created, formatted, and your data is now ready to be restored from your backup. You do not need to reboot Windows NT to have this change made.
Note: With the primary SYS volume already created, you cannot expand the actual size of the SYS Volume. NetWare simply will not recognize the new disk space. You can only create a new disk array using the ServeRAID Manager program, then down the server, type server at the DOS prompt,
scan for new devices, and create a new volume.
Can the server ping the client machine? No! The problem is on the server end...
Can the client ping the server? No! The problem is on the client end...
Can they both ping each other? Yes! You can successfully use the program above...
