[CentOS] LUKS on EL6 / enable block device after reboot

Is there an easy way (cli) to enable a luks encrypted partition 
after reboot (a partition that was not enabled while booting, 
because not in the crypttab). 

I can execute the necessary command stack [1] but just wondering if 
there is an "enterprise/easy" way to do that ...

[1] cryptsetup luksOpen $(blkid -t TYPE="crypto_LUKS" -o device) \
    luks-$(cryptsetup luksUUID $(blkid -t TYPE="crypto_LUKS" -o device))
