Physical volume disappeared on reboot - help!

Latest response

Any guidance appreciated...

RHEL on VMware, added a new 1.4TB virtual disk a few weeks ago, created a new PV, logical volume and volume group, mounted it at /var/www/vhosts/mountpoint, and all was good.

Server rebooted this morning, and won't start. Have removed new mount point from /etc/fstab and it starts fine.

No sign of my VG, LV or PV! Argggh... Device is connected in VMWare and visible as /dev/sdc.

(It was in a VG called vg_vhosts_stmacks)

[root@callisto ~]# lvmdiskscan
