SAN HBA Setup

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

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

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