LUNS not getting visible

[Scorpianzzz]

Hi,

I have configured a rx2660 server and presented LUNS to it from EVA4400. The OS installed is 11i v2.

When the system is shutdowned and then powered on, all the LUNS are visible and everything is fine...

Now when i reboot the system, the LUNS disappears...

1. When I do
# vgdisplay -v vg01

vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "vg01".

2. When I do
# vgchange -a y vg01

vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c4t0d1":
The path of the physical volume refers to a device that does not
exist, or is not configured into the kernel.
vgchange: The path of the physical volume refers to a device that does not
exist, or is not configured into the kernel.
vgchange: Warning: couldn't query physical volume "/dev/dsk/c4t0d1":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query physical volume "/dev/dsk/c6t0d1":

this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.

3. But when I do
# ioscan -fnCdisk

It shows all physical volume as CLAIMED
... and then ALLOWS me to ACTIVATE Volume Group "vg01"

The file /etc/lvmtab also looks fine...

Can ne1 help me out with this problem. Its urgent...

Regards,
Rajiv

there is no problem with the disk...
after shutting down and starting the system, everythings works fine...

its only when reboot... the server/os causes the problem

The main culprit was the FC card... replaced it and it worked fine...


Thanks again...
