Fibre Channel Adapter Device Driver Maximum I/O Size
Set the max_xfer_size attribute for optimal AIX host operation over FC with PowerStore.
Prerequisites
The max_xfer_size FC HBA adapter device driver attribute for the fscsi device controls the maximum I/O size that the
adapter device driver can handle. This attribute also controls a memory area the adapter uses for data transfers.
For optimal AIX host operation over FC with PowerStore, perform the following steps:
Steps
1. Run the following command on all FC adapters that are connected to PowerStore:
chdev -l fcs0 -a max_xfer_size=0x100000 -P
2. Reboot the AIX host to apply the max_xfer_size setting adjustments.
NOTE: For virtualized AIX hosts, make sure to apply the max_xfer_size setting adjustments on all LPARs of the host
that is connected to PowerStore storage.
Dell EMC AIX ODM Installation
This topic provides an introduction to Dell EMC ODM.
The Object Data Manager (ODM) is a database of system and device configuration information that is integrated into the AIX
operating system. Information is stored and maintained as objects with associated characteristics. The Dell EMC ODM support
package contains a series of installable filesets. These filesets are used to update the AIX ODM with customized Dell EMC
storage device configuration attributes.
Dell EMC AIX ODM Installation Requirements
This section outlines the requirements for Dell EMC AIX ODM installation.
To meet the Dell EMC storage cluster requirements, you must install the correct Dell EMC ODM filesets to support Fibre
Channel attachment to the PowerStore cluster.
The minimum ODM and AIX operating system versions that are supported with PowerStore and native MPIO are:
DellEMC.AIX.6.2.0.1.tar.Z -> For AIX 7.1, 7.2 and VIOS 3.1.0
PowerStore AIX ODM software package needs to be updated to version 6.2.0.1 prior to running PowerStoreOS 1.0.2.0.5.003 (or
later) with PowerPath. PowerStoreOS SP2 contains a change to the PowerStore cluster serial number that requires this new
ODM package version. A reboot of the connected AIX host is required for this change to take effect.
To install the Dell EMC fileset:
1. Download the correct Dell EMC ODM fileset version and place it in the /tmp/ODM directory.
2. Untar the DellEMC.AIX.6.2.0.1.tar.Z file, using the following command:
uncompress DellEMC.AIX.6.2.0.1.tar.Z
tar -xvf DellEMC.AIX.6.2.0.1.tar.Z
3. Run the following command to create a table of contents file:
inutoc .
4. Run the following command to install the following filesets to support native MPIO:
installp -ad . EMC.PowerStore.aix.rte EMC.PowerStore.fcp.MPIO.rte
