Miscellaneous Planning and Procedures
Direct-connect dual-host clustering configurations
For CLARiiON CX200 series direct-connect dual-host cluster
configurations only with QLA234x adapters, you must follow all
procedures described in this section.
Check for an updated
adapter driver
For CLARiiON CX200 series direct-connect dual-host cluster
configurations with only QLA234x adapters, you may need a
separate driver and firmware download. The EMC Support Matrix
notes whether separate driver and firmware files are required.
For each adapter determined to require updated firmware and
drivers, follow the instructions on “Downloading latest QLogic
drivers/firmware/BIOS files” on page 16. Be sure to reference the
Name and Description fields to select the correct CX200 series
direct-connect dual-host cluster-compatible files.
Reconfigure the
adapter jumper
For CLARiiON CX200 series direct-connect dual-host cluster
configurations with only QLA234x adapters, you must change the
default adapter optic jumper position:
IMPORTANT
Modifying the jumper setting without using the recommended
firmware/drivers can cause the adapter to lose connectivity.
1. Remove the adapter from the server as instructed by your server
guide.
2. Locate jumper(s) J3 (QLA2340) or J3 and J4 (QLA2342), shown in
Figure 124 on page 177.
