I'll be upgrading a server from 8.2 to 9.0 soon. On it, I currently have
the following zpool:
----------
[0]# zpool status
pool: hal.1
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
hal.1 ONLINE 0 0 0
raidz2 ONLINE 0 0 0
ad10p3 ONLINE 0 0 0
ad12p3 ONLINE 0 0 0
ad14p3 ONLINE 0 0 0
ad16p3 ONLINE 0 0 0
ad18p3 ONLINE 0 0 0
ad20p3 ONLINE 0 0 0
errors: No known data errors

I would like to do two things:
1) Wire the ATA CAM disks such that ad10 -> ada0, ad12 -> ada1, etc.
2) Change the zpool to use the then newly available ada0p3, ada1p3, ...,
ada5p3 gparts.
Ultimately, I want to set sysctl kern.cam.ada.legacy_aliases=0.
Please advise on how best to achieve this.
Regards,
Martin
