[OpenIndiana-discuss] problem replacing a disk by a bigger one: not yet solved

[Marc Lobelle]

I think I know where the problem is: "# bootadm install-bootloader -P 
rpool " installs what is needed to boot in UEFI mode and this is not 
possible on a computer that can be dual booted with windows, even in my 
case where openindiana and windows are on 2 different ssd. And this 
operation made all the disks in rpool unbootable on this system. I 
should probably have run"# bootadm install-bootloader -Mf -P rpool " to 
force installation of a "legacy" MDB boot.

So, at this point, the only way to run openindiana on the system to fix 
this issue is running it from the installation dvd. However, if I type 
zpool list on that, I do not see any pool even if I boot it with 
reconfigure. How can I install the booting stuff on the internal disk of 
the system from an openidiana running on the installation dvd. Some 
versions of bootadm allow specifying the device on which to install the 
booting  stuff, but not the bootdm on openindiana.

Thanks for your help
