Pausing I/O - Adaptec DuraStor 7220SS User Manual

Pausing I/O

The DuraStor 312R storage enclosure allows hot-swapping
(removing and replacing disk drives while SCSI bus activity
continues). The Hot Swap Pause Function suspends activity on all
device channels used in the controller and protects data integrity
on the connected disk drives and arrays.
Note: Pausing I/O halts active I/O to the host.
Caution: If you are not using the DuraStor Storage

Subsystem, refer to your enclosure's documentation before
you attempt to hot-swap disk drives.

The Utilities menu appears.
2

or an operating system time-out may occur. The pause
limitation before time-out varies according to the
operating system. For example, in Windows NT, the
