[OpenIndiana-discuss] how to boot OI installed on IDE HD from USB enclosure

[Erdos New]

 hi, i'm the OP and am trying to get a solution on this.

this is my situation:
1.  I've installed OI previously onto an IDE HD.  the HD was then put into an USB enclosure.  obviously OI fails to boot. 
2.  Now i've downloaded the latest 2017.10 OI hipster image and put on an USB thumb drive.  it boots flawlessly.
3.  can i use this USB OI image to import/export rpool for the OI located in the usb housing, per JIm's suggestion?

 

i'm a novice with OI and would like detailed guide from anyone knowledgeable on how to accomplish my goal.

This issue prohibits e.g. easy switching of ide/ahci modes for sata disks, dual-booting (vm/hw from same partition) and root disk re-attachment. Logic for non-rpool import is different, so the issue is not there. What you can do is either boot from another media (livecd or liveusb), import the rpool and export it. If the device enumeration happens to be okay (and with usb it is not a given) - you'd be in luck, and the hdd will boot afterwards.Alternately you can set up a firefly image to your rpool (miniroot matching the kernel should suffice, or a dedicated BE with iso image's contents) which does not require extra devices and risk of different device-path enumeration. If you're familiar with solaris 10 failsafe boots - firefly delivers that. See my github repo for illumos-zfs-splitroot scripts, they have a feature to integrate a firefly image as a boot option among beadm upgrade extensions.Finally, make sure you don't use USB3 ports and reader, or that your OI Hipster installation has been pre-updated to have experimental support of USB3 (should've been added a month or two back).Jim--Typos courtesy of K-9 Mail on my Samsung Android_______________________________________________openindiana-discuss mailing listopenindiana-discuss at openindiana.orghttps://openindiana.org/mailman/listinfo/openindiana-discuss
