Can anyone explain why this is, or needs to be?
In some systems, disks are named c0t0d0 etc
In some systems, they're named like this: c0t5000C5003424396Bd0
Worse yet...
In my present system,
foo=5000C5003424396B
bar=600C0FF000000000092C4D22A708D800
when I run format, I see c0t${foo}d0
If I ls /dev/rdsk/c0t${foo}* I see all the usual suspects... p0 to p4, and
s0 to s15 ... But I don't see any "d0" without any "p" or "s"
If I ls /dev/rdsk/*d0 then I see $bar
Here's why I care:
I installed s11e to a partition of a 2T drive. Now I want to mirror it, so
I want to replicate the fdisk partitions & partition slices onto the 2nd
disk... Nothing I do inside of "format" seems to make them identical, so I
considered using a low-level dd copy of the raw disk, but the device name
for the raw disk doesn't exist (nothing /dev/rdsk/*d0 matching the name of
the disk in my zpool), unless it's one of those other $bar things... In
which case I don't know which one is which. I have a 50/50 chance of doing
it right, or destroying the original. That's all assuming it's even valid
to attempt doing such a thing.
Right now, the only technique I can think of that will work is ... I'll
ignore the partition&slice tables on the original disk, and create a new
fdisk partition & partition slice scheme on the 2nd disk as I wish. Then
I'll zfs send the rpool onto the 2nd disk, install grub etc, and wipe out
the first disk. Boot from the 2nd disk. Then re-partition the first disk
the same as the 2nd disk and start mirroring. This sounds like a pointless
hassle that must be avoidable SOME how.
;-) Thanks for any answers/info/suggestions.
