Host HBA installation and configuration
This document describes how to install a particular HBA on diffferent O/S.
AIXTo display what HBA's are installed
To set the configuration you must carry out the following:
To discover the SAN devices
HP
To display what HBA's are installed.
The HP systems Volume address setting must be enabledon the SAN, you can check this will the following command.

SUN
To display what HBA's are installed.
To set the configuration you must carry out the following:
Changes to /etc/system
SCSI throttle | set sd:sd_max_throttle=20 |
Enable wide SCSI | set scsi_options=0x7F8 |
SCSI I/O timeout value | sd:sd_io_time=0x3c (with powerpath) |
Changes to HBA driver (/kernel/drv/lpfc.conf)
fcp-bind-WWNN=16 |
automap=2 |
fcp-on=1 |
lun-queue-depth=20 |
tgt-queue-depth=512 |
no-device-delay=1 (without PP/DMP) 0 (with PP/DMP) |
xmt-que-size=256 |
scan-down=0 |
linkdown-tmo=0 (without PP/DMP) 60 (with PP/DMP) |
Persistent Binding
Both the lpfc.conf and sd.conf files need to be updated. General format is
name="sd" parent="lpfc" target="X" lun="Y" hba="lpfcZ"
X is the target number that corresponds to the fcp_bindWWNID lpfcZtX
Y is the LUN number that corresponds to symmetrix volume mapping on the symmetrix port WWN or HLU on the clariion
Z is the lpfc drive instance number that corresponds to the fcp_bind_WWID lpfcZtX

Windows
To display what HBA's are installed.
To set the configuration you must carry out the following:
Registry changes
See the Host connectivity guide for windows or use the Emulex configuration tool to set the below registry settings.
Arbitrated loop without powerpath/ATF | InitLinkFlags=0x00000000 (arbitrated loop, auto-link speed) WaitReady=45 LinkDown=45 TranslateQueueFull=1 |
Arbitrated loop with powerpath/ATF | InitLinkFlags=0x00000000 (arbitrated loop, auto-link speed) WaitReady=10 LinkDown=10 |
Fabric without powerpath/ATF | InitLinkFlags=0x00000002 (fabric, auto-link speed) WaitReady=45 LinkDown=45 TranslateQueueFull=1 |
Fabric with powerpath/ATF | InitLinkFlags=0x00000002 (fabric, auto-link speed) WaitReady=10 LinkDown=10 |
Modifying the EMC environment
In the shortcut for the elxcfg add the "--emc" option to the target option.
