Is there a way to know where grub is installed? I have a few servers

It won't hurt to re-install. The tricky part is knowing where the 2nd
drive in the set will appear when the first fails so you can do the
configuration correctly.
So long as you have all the necessary grub files, there is not much
danger. Even if you are missing a config file on this side of the mirror
(impossible...) so long as you load grub stage 2, you will have the
power you need to continue if you have access (eg: via serial)
Worst case: boot the install cd with 'linux rescue' at the boot prompt,
let it detect and mount the system partitions, do the chroot it
suggests, then 'grub-install /dev/sda' (or wherever the boot drive
appears now), exit twice, and remove the CD as you reboot.
