    # lvm pvscan <-- should see hdb as a PV in a VG
    # lvm vgscan
    # lvm lvscan <-- tells you the LV name that has the fs
    # lvm lvchange -a y /dev/$VGNAME/$LVNAME <-- activates the LV
    # mount /dev/$VGNAME/$LVNAME 

    Thanks for the suggestions.

    I loaded a new hdd hda with 4.3 single cd server; then i
    powered down and connected the hdb from the failed system and
    rebooted; the hdb was not found using the commands above  so i
    was not able to mount

These are done without the drive mounted. Also, pvscan -v might be useful. The fdisk -l that someone suggested will probably the first and most useful step. It will tell you whether hdb was a standard ext* or LVM partition.
