Appendix A: Configuring a QLogic FibreCache 10000

Series Adapter Cluster

Follow these steps to create a cluster and enable a cache on the 10000
Series adapter.

insert the 10000 Series adapter and PCie

flash daughter card into the

server.

Connect the 10000 Series adapter to the fabric switch.

On the fabric switch, zone all of the 10000 Series adapters (at least one
in each server) onto the same zone. this step is required to allow the
10000 Series adapters to communicate with each other for the caching
and i/O functions.

Use the 10000 Series adapter host CLi

utility to perform the

remaining steps.

issue the

list adapters command to present all of the adapters

that are visible in the fabric zone. this step provides the Fibre Channel
adapter iD for each of the 10000 Series adapters that are in the zone.

issue the

create cluster command, where the -clusterid

keyword indicates the iD to be used for the new cluster and the
-secondary keyword indicates the iD of the Fibre Channel adapter

that will be the secondary of the new cluster. this step creates a two-
node cluster of 10000 Series adapters.

issue the

add member command to add other members (10000

Series adapters) to complete the cluster.

1 the host CLi utility is available for download from the QLogic Downloads and Documentation Web page:

http://driverdownloads.qlogic.com/

Set the cache pool for each 10000 Series adapter as follows:

issue the

show pool command to view the available storage

for the 10000 Series adapter cache pool.

issue the

set pool command to specify the largest amount

possible for each 10000 Series adapter.

all of the QLogic 10000 Series Fibre Channel adapters are now ready to
identify which LUNs each will “own” for caching purposes.

issue the

show lun command to list all of the LUNs that have been

mapped to the 10000 Series adapters through the fabric.

identify the LUN by one of the following:

[-lun_serial=<LUN Page 0x80 serial number>]

[-lun_wwuln=<WWULN>]

[-lun_any_wwuln=<LUN WWULN, or Page 0x80

serial number designator

[-lun_number=<logical unit number>]

[-fc_target=<Fibre Channel target name>]

the cluster is now configured.

CAUTION:

to ensure data integrity, any LUN must be cached by one and

only one QLogic 10000 Series Fibre Channel adapter. each 10000 Series
adapter may cache up to 256 LUNs. all 10000 Series adapters in the cluster
must be zoned to be visible to each other.
