when I try to actived /dev/vgXIS the system show me next:

# vgchange -a y /dev/vgXIS
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c1t6d0":
Cross-device link
vgchange: Warning: couldn't query physical volume "/dev/dsk/c1t6d0":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "/dev/vgXIS":
Quorum not present, or some physical volume(s) are missing.


And ioscan show me that:
# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
============================================================================
disk 0 8/0/19/0.6.0 sdisk CLAIMED DEVICE SEAGATE ST34572WS

disk 2 8/16/5.6.0 sdisk CLAIMED DEVICE QUANTUM FIREBALL SE2.1S
/dev/dsk/c1t6d0 /dev/rdsk/c1t6d0

A very common cause of a cross-device link is a duplicated LVM minor device number.

Do this:

ls -l /dev/vg*/group and make sure that all the minor device numbers are unique.

Also check in /etc/lvmtab to find out how many devices are associated and make sure you still have access to all of them. Or check in "vgdislay -v vgname "output if you have the old logs available

Thanks for your help, I resolved it with

vgcfgrestore -n /dev/vgXIS /dev/rdsk/c1t6d0

and

vgchange -a y /dev/vgXIS

thanks
