Host HBA installation and configuration

This document describes how to install a particular HBA on diffferent O/S.
AIX To display what HBA's are installed

• lscfg
• lscfg -v -l fcs*

To set the configuration you must carry out the following:

• List HBA WWN and entry on system
• Determine code level of OS and HBA
• Download and install EMC ODM support fileset
• run /usr/lpp/Symmetrix/bin/emc_cfgmgr (symmetrix) or /usr/lpp/emc/CLARiiON/bin/emc_cfgmgr (clariion)

To discover the SAN devices

• /usr/lpp/EMC/Symmetrix/bin/emc_cfgmgr -v if the above does not work reboot server

HP
To display what HBA's are installed.

• /opt/fcms/bin/fcmsutil /dev/td# (A5158A HBA)
• /opt/fc/bin/fcutil /dev/fcs# (A6685A HBA)

On a HP system there is no additional software to install. The HP systems Volume address setting must be enabledon the SAN, you can check this will the following command.

• symcfg -sid <SYMM ID> -FA all list (confirm that the volume set addressing is set to yes)

To discover the SAN devices

• ioscan -fnC disk (scans hardware busses for devices according to class)
• insf -e (install special device files)

SUN
To display what HBA's are installed.

• prtdiag -v
• dmesg
• cat /var/adm/messages | grep -i wwn | more

To set the configuration you must carry out the following:

• changes to the /etc/system file
• HBA driver modifications
• Persistent binding (HBA and SD driver config file)
• EMC recommended changes
• Install the Sun StorEdge SAN Foundation package

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) sd:sd_io_time=0x78 (without 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
To discover the SAN devices

• disk;devlinks;devalias (solaris 2.6)
• devfsadm (solaris 2.8)
• /usr/sbin/update_drv -f sd (solaris 2.9 >)

Windows
To display what HBA's are installed.

• use admin tool "device manager"

To set the configuration you must carry out the following:

• Registry edits
• EMC recommended changes
• Install emulex exlcfg utility

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.
To discover the SAN devices

• control panel -> admin tools -> computer management -> select disk management -> (top menu)action -> rescan tools

Red Hat

1. Install the EMC rpms
   
2. echo "scsi-qlascan" > /proc/scsi/qla2300/[0,1]
   
3. cd /apps/packages/EMC
   
4. ./rescan-scsi-bus.sh --luns=[list,range-range]
   
5. powermt config (to see the new lun[s] in Power Path)
   
6. powermt -display dev=all
