102 Configuration: Disk Groups and Virtual Disks
A disk group must be organized according to its related tasks and subtasks.
For example, if you create a disk group for the Accounting Department, you
can create virtual disks that match the different types of accounting
transactions performed in the department: Accounts Receivable (AR),
Accounts Payable (AP), internal billing, and so forth. In this scenario, the AR
and AP virtual disks probably need more capacity than the internal billing
virtual disk.
NOTE: In Linux, the host must be rebooted after deleting virtual disks to reset the
/dev entries.
NOTE: Before you can use a virtual disk, you must register the disk with the host
systems. See "Host-to-Virtual Disk Mapping" on page 125.
