SUN/SOLARIS
___________
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: ( Plz ignore 3 equal sign when u edit the file)

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 lpfcZtXY is the LUN number that corresponds to symmetrix volume mapping on the symmetrix port WWN or HLU on the clariionZ 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

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

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 -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)

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

Hope this will be documented and useful info for novice user.
