Operating System Considerations
Client provides a graphical interface that replaces your controller’s CLI interface.
It cannot, however, perform all operating system configuration necessary to
make your subsystem’s virtual disks visible to the user in the operating system.
When you create or delete virtual disks using either the CLI or Client, you are
adding or removing “disks” in the subsystem in a manner similar to plugging or
unplugging physical disk drives on the host bus. In either case, there are certain
operating system configuration actions you must perform to make these “disks”
visible or invisible to the operating system’s file system.
Windows NT Configuration
On a Windows NT host and after you create or delete a virtual disk using Client
(or the CLI), you must perform the following steps to properly configure the NT
file system to recognize your changes.
1. Boot the host system. This action has the effect of forcing the NT Disk
Administrator to recognize added virtual disks as raw disks, available for
use. It also notes that deleted virtual disks are no longer present.
2. Create file system partitions on your disks. When you create a virtual disk in
the controller, you have the option to partition it at the controller level in any
way you wish, as long as you create at least one partition per disk. Each of
the controller-level partitions you create becomes a virtual disk, visible to
the host. In Disk Administrator, you must partition these newly added virtual
disks at NT’s file system (NTSF) level.
3. Once you have partitioned your drives in Windows NT, the file system
assigns each drive a unique drive letter. Make a note of the drive letters
assigned.
4. Format your disks—You must format each newly added disk in NT to make
it fully usable as an NT-compatible disk.
5. Start the Agent Configurator by double clicking its icon in the Command
Console Start Menu group.
6. Navigate through the menus until a popup appears, prompting you to rescan
your subsystems. Click Yes to perform the rescan and display a list of
subsystems.
