Mirroring Disks in Your Express5800/320Ma System

4-24 Express5800/320Ma: System Administrator’s Guide

EMC Attached Storage

If an optional EMC CLARiiON

, EMC Symmetrix

, or EMC CLARiiON AX100 Storage

System is installed in your system, Fibre Channel Controller nodes will appear

beneath the PCI Slot Info nodes in which the adapters are installed.

NOTE

System disks cannot reside in an EMC attached storage

system. See “Mirroring Disks in Your Express5800/320Ma

System” on page 4-24 for details.

The values that the Op State: State and Op State: Reason properties can take vary

depending on whether EMC PowerPath

software is running. See Table 4-2 for details.

When you reattach a cable between your EMC storage system and the PCI adapters

in your system, the connection state may not be immediately reflected in ftSMC. To

update ftSMC, issue the command powermnt restore in PowerPath, from Run on the

Start menu, or from a command prompt. The information in ftSMC should be updated

after about 15 seconds.
