Starting the RAID Configuration Program

Starting the RAID Configuration Program

You can run the IBM RAID configuration Program fom Diskette or from the ServerGuide CD . It will be autom. invoked from the ServerGuide CD if the disk array has never been partitioned and if there is no user data present. However, updatet configuration information must be written to diskette . If you have not yet created the IBM SCSI-2 Fast/Wide Streaming-RAID Adapter/A Option Diskette (RAID controller diskette), go to 'Using the CD-ROM Drive and ServerGuide'

To start the RAID configuration program:

Insert the IBM SCSI-2 Fast/Wide PCI-Bus Adapter Configuration Option Diskette into the primary diskette drive and power-on the system. If the system already is powered-on, press Ctrl+Alt+Del. From the PC DOS start-up menu, select Start RAID Configuration Program, then press Enter.

If you have more than one RAID adapter installed, you will get an adapter selection screen similar to the following, otherwise, the Main Menu appears.

NOTE:

The version numbers and slot numbers on the screens might be different.
The primary diskette drive is the first diskette drive that the system tries to start from.

You can select Help from any menu. To return to the previous screen or to the previous work area of a screen, press Esc. To select a menu item, press the number of the item or use the Up Arrow (

) key or Down Arrow (

) key to highlight the item, then press Enter.

The Main Menu contains the following choices:

Help: Select this choice when you need additional information.
View configuration: Select this choice to see the existing disk array configuration.
Create/delete array: Select this choice to define a hot-spare drive, to select the drives for an array you want to create, or to delete an existing array. The Create/delete array screen also has choices for defining a logical drive and formatting a drive.
Whenever you make changes to the disk-array configuration and select Exit, the Confirm pop-up window will appear. You must select Yes to save and activate the changes.
Initialize/synchronize array: Select this choice after creating an array to:
- Synchronize logical drive: Select this choice to recompute and rewrite the parity data on the drive for RAID levels 1 and 5. This selection does not alter data on the drive. The synchronization process can be done on multiple logical drives.
Rebuild device: Select this choice to rebuild logical drives. The rebuild operation is supported only for RAID levels 1 and 5.
Advanced functions: Select this choice to change the write policy (the way data is written to the drive), to save the configuration information to a diskette, to restore it from a diskette, or to change RAID parameters. This choice also allows you to do a low-level format.
Drive information: Select this choice to view information about the SCSI devices (hard disk, CD-ROM, tape, and so on) connected to the RAID adapter.
Exit: Select this choice to leave the Main Menu.
