How to allocate LUN from Symmetrix to a Windows cluster server using SYMLCLI

Windows 2003 or 2008 ?

since windows in a cluster.

need to create the meta on the symmetrix & map to the FA ports to which your windows box(cluster) is zoned.

since it is in a cluster if Host A has 2 HBA & Host B has 2 HBA then there will 4 HBA for the windows cluster take the 4 WWN & mask the devices to it.

this will done the alloaction for the wondows cluster

Its Windows 2008

you need to make sure that Windows 2008 is connected either through FAs that have correct flags set on them, or set the flags manually using "symmask hba_flags" command. You need to set these flags:OS2007,SC3,SPC-2,C

second thing is you need to enable persistent reservation bit on the devices that will be presented to the cluster:

set device 0843 Attribute=SCSI3_persist_reserv;
set device 0216 Attribute=SCSI3_persist_reserv;

once you have devices presented, it's much easier on Windows 2008 to configure failover cluster, start the wizard and it will walk you through everything.

Thanks a lot Dynamox and emcsanadmin.

Thank you Dynamox,

Do I need to allocate the LUNS to 4 HBAa ( 2 HBAs on each server in cluster) and after that follow the  failover cluster wizard?
