Alas there is no preinstalled failsafe sine OpenSolaris. I had reasonable success using Firefly as a BE and/or as a miniroot stored in the main BE, and published scripts I use to manage that setup - mostly needed to switch device paths saved into rpool when I dual-boot OI as VM or Physical OS on my laptop.

If your system can boot from CD/DVD or USB, I suggest you take the install media, or firefly, or ... and zpool import your pools and perhaps mount the desired rootfs to manage it. For just GRUB menu setup and zpool settings you shouldn't need to even mount rootfs datasets.
