LVM: VG 64 0x030000: Lost quorum.

I have created a vg03 on EVA3000 yesterday,today I saw the "unavailbe" status with all of the PVs in vg03 when I used "vgdisplay -v vg03" . then I used below command to check :
#diskinfo /dev/rdsk/c10t0d1 (can see the info.)
#ioscan -fnCdisk (can see the CLAIMED status with those devices in vg03 .)
All of PVs in vg03 turn to "availbel" status after reboot the hosts .
checked the syslog.log, found some messages as below:

Re: LVM: VG 64 0x030000: Lost quorum.

more then 50 % disk should be available in VG to activate volume group. If no. of disks available is less then 50% means Quorum.
You can use lvchange -q n to disable quorum requirment but in this case if lost disks has some data. you data will be not be consistent.

You have installed and are using Secure Path for HP-UX yes? Your not attempting to use PVlinks with the EVA are you, it won't work - you must Secure Path.
