Data Domain: Configuring DD Boost Fibre Channel devices for AIX

• ODM definitions 6.0.0.6 (AIX required version 7.1 or 7.2)
• ODM definitions 6.1.0.0 or higher (minimum AIX required version 6.1)*

Data Domain Configuration

1. Create a new Access Group for DD Boost FC service.

   # ddboost fc group create <group-name>

2. Add one or more initiators.

   # ddboost fc group add <group-name> initiator <initiator-spec>

3. Add DFC devices to the Access Group of type "disk."

   # ddboost fc group add <group-name> device-set [count <count>] [endpoint {all | none | <endpoint-list>}] [disk]

   • If "disk" is not specified, then the default DFC device type, Processor, is added.
4. Review the Access Group configuration and confirm that there are only disk-type devices.

   # ddboost fc group show detailed <group-name>
   
   DDBoost FC Group: <group-name>
   State: active
   
   DDBoost FC Initiators:
   Initiator Name   System Address
   --------------   -----------------------
   <initiator alias> <initiator wwpn>
   --------------   -----------------------
   
   DDBoost FC Devices:
   Device Name     LUN   Endpoints
   -------------   ---   ---------
   ddboost-disk0     0         all
   ddboost-disk1     1         all
   ddboost-disk2     2         all
   ddboost-disk3     3         all
   ddboost-disk4     4         all
   -------------   ---   ---------

   • Separate groups are required for devices that must be shared to both disk-based and processor-based clients.
   • The same initiator cannot be used for both processor and disk.

AIX host configuration

1. Remove any existing Data Domain disks that are recognized as "Other FC SCSI Disk Drive" by the system.

   # lsdev -Cc disk | grep "Other FC SCSI Disk Drive" | awk { print $1 } | xargs -n1 rmdev -dl

2. Download "AIX ODM Kit 6.2.0.1" or higher from the Dell support site.
3. Copy the file to the AIX host in a temporary directory.
4. Install the ODM package and discover new DFC devices.

   # uncompress DellEMC.AIX.6.2.0.1.tar.Z
   # tar -xf DellEMC.AIX.6.2.0.1.tar
   # cp DellEMC.AIX.6.2.0.1 /usr/sys/inst.images/
   # cd /usr/sys/inst.images 
   # inutoc .
   # installp -ac -gx -d . EMC.DataDomain.aix.rte
   # installp -ac -gx -d . EMC.DataDomain.fcp.MPIO.rte
   # cfgmgr

5. Confirm that devices have been configured.

   # lscfg -vp | grep MPIO

6. Optionally, test device visibility and connection with the ddpconnchk tool.

• The AIX DD Boost plug-in searches for DDdfc devices before it looks for hdisk devices
• If DFC processor devices were configured before and are being replaced with DFC disk devices, follow these steps before starting with the new configuration:
  1. Remove the DFC processor devices configuration for the specific AIX host on Data Domain.
  2. Uninstall DDdfc driver.
  3. Delete DDdfc devices in AIX.

     # installp -u DDdfc.rte   
     # rmdev -Rdl DDdfc
     # cfmgr

• The AIX 'smitty' command can also be used to install the Data Domain ODM file sets.
