Hot-Plug Disk Drive Removal
and Replacement Guidelines for
Compaq Smart Array
Controllers
Abstract:
The purpose of this paper is to communicate to customers
the guidelines for implementing hot-plug removal and replacement
of hard drives when using Compaq Smart Array Controllers.
Compaq is fully committed to providing the ideal client/server high
availability solution for customers.
High availability features in
Compaq Smart Array Controllers include hot-pluggable hard drives.
With hot-pluggable hard drives, customers can remove and replace
one or several drives within a server while the system is online for
rapid recovery while minimizing interruption of the network.
In order to maximize high availability, Compaq has issued customer
guidelines on extending and implementing the removal and
replacement of hot-pluggable hard drives.
