1. ODM UPDATE OVERVIEW
##########################################
For new HDLM installations on AIX implementing HDLM v5.9.x and later versions, the following ODMs should be installed:
- 5.0.0.1: initial install fileset (reboot required)
- 5.0.0.5: Hitachi storage array model support update*
- 5.0.52.1: Hitachi storage array model support update
- 5.0.52.2: Hitachi storage array model support update
- 5.0.52.3: Hitachi storage array model support update
For existing hosts being upgrading to HDLM v5.9.x or later, please verify that the above ODM updates are already installed.
*Please note that existing HDLM hosts may have ODM update 5.0.0.4 or 5.0.1.4 installed instead of 5.0.0.5. This is OK.

4. ODM UPDATE INSTALLATION INSTRUCTIONS
##########################################
To install the new version of HTC_ODM updates for AIX:
(1) Log-in as superuser
(2) Mount the CD-ROM
(3) Copy HTCODM3.tar to the AIX host (/usr/sys/inst.images):
<Example>
# cp HTCODM3.tar /usr/sys/inst.images
(4) Extract HTCODM3.tar
<Example>
# cd /usr/sys/inst.images
# tar xvf HTCODM3.tar
(5) Five HTC_ODM packages (HTC_FC_ODM_5001I and HTC_FC_ODM_5005U and HTC_FC_ODM_50521U and HTC_FC_ODM_50522U and HTC_FC_ODM_50523U) are created
(6) Create a new .toc file
<Example>
# cd /usr/sys/inst.images
# inutoc .
(7) Use installp to install the AIX support fileset:
<Example>
# smitty install
(8) Select Install and Update Software.
(9) Select Install Software.
(10) You will be prompted for an input device. Enter the directory whether the fileset was copied.
(11) Select F4 to list the available installation packages.
(12) Use the F7 key to select the following filesets:
"5.0.0.1 AIX Support for Hitachi Disk Arrays"
"5.0.0.5 AIX Support for Hitachi Disk Arrays(Update)"
"5.0.52.1 AIX Support for Hitachi Disk Arrays(Update)"
"5.0.52.2 AIX Support for Hitachi Disk Arrays(Update)
"5.0.52.3 AIX Support for Hitachi Disk Arrays(Update)"
and then select Enter.
[Note] In case that some packages are already installed, select the necessary package only. For example, if Hitachi.aix.support.rte 5.0.0.4, 5.0.0.5, or 5.0.1.4 is already installed, then "5.0.52.1 AIX Support for Hitachi Disk Arrays(Update)" should be selected.
(13) Select Enter to start the installation process
(14) If necessary, remove any Hitachi devices already defined as "Other FC SCSI disk drive".
- To remove one device:
# rmdev -dl hdisk(n)
- To remove all devices on a path:
# rmdev -dl fscsi(n) -R
(15) Reboot AIX.
(16) Confirm that the disk device attributes have the following values:
# lsattr -E -l hdisk(n)
pvid ***
queue_depth 2
q_type simple
q_err yes
clr_q no
rw_timeout 60
start_timeout 60
reassign_timeout 120
reserve_policy single_path
(17) If the value is modified when HTC_ODM is applied, be sure to change the value after committing HTC_ODM if necessary. For example, if the queue_depth was set to 4, the chdev command will have to be run to change it back for all hdisks.
[Note] Please note that the default IBM rw timeout and queue depth values are different than those recommended for Hitachi devices. Hitachi recommends that you set the queue_depth parameter of an hdisk for an HDLM-managed device to a value greater than or equal to the number of paths that are connected to the hdisk. For example, to specify the queue depth parameter for an hdisk, you may execute the chdev command as follows:
<Example>
# chdev -l hdiskn -a queue_depth=8 -a rw_timeout=60
##########################################
5. ODM UPDATE UNINSTALLATION INSTRUCTIONS
##########################################
(1) Remove all Hitachi LUNs from the system using the rmdev command:
- To remove one device:
# rmdev -dl hdisk(n)
- To remove all devices for a path:
# rmdev -dl fscsi(n) -R
(2) Enter smitty install from command line.
<Example>
# smitty install
(3) Select Software Maintenance and Utilities.
(4) Select Remove Installed Software.
(5) Select F4 for SOFTWARE to list all installed software.
(6) Select (/) for Hitachi
(7) Select the package to remove by pressing F7 and then Enter
(8) Use either the Tab key or F4 to change PREVIEW only to No.
(9) Select Enter to confirm the warning message.
(10) Reboot AIX.
##########################################
6. IMPORTANT TECHNICAL CONSIDERATIONS
##########################################
(1) The AIX support non-MPIO ODM update(HTC_ODM) and the MPIO ODM update(HTC_MPIO_ODM) can not co-exist on the same server.
For example, the following ODM updates should NOT be installed when using HDLM:
devices.fcp.disk.Hitachi.array.mpio.rte 5.4.0.0 AIX MPIO Support for Hitachi Disk Arrays(New Install)
devices.fcp.disk.Hitachi.array.mpio.rte 5.4.0.1 AIX MPIO Support for Hitachi Disk Arrays(New Update)
devices.fcp.disk.Hitachi.array.mpio.rte 5.4.0.2 AIX MPIO Support for Hitachi Disk Arrays(New Update)
(2) The AIX support filesets that are applied must be committed.
