1.4.3 I/O Multipath with DR

The Path Redundant capability by I/O Multipath can be utilized to maintain uninterrupted access to the media in case of a system board detach. An I/O device can be configured such that it can be accessed from two different system boards. Even if one of the system boards is detached, the I/O device remains accessible. However, I/O performance may be degraded because the number of redundant paths is reduced. Without I/O Multipath, all I/O devices on the system board must be deactivated before the system board can be detached.

Connection scripts should be used to perform the necessary I/O Multipath operation for the DR.
