are the disk/sas controller the same on both server?
Seemingly no. I don't see the output of "format" on Server2,
but for Server1 I see that the 3TB disks are used as IDE
devices (probably with motherboard SATA-IDE emulation?)
while on Server2 addressing goes like SAS with WWN names.
Correct, the servers are all different.
Server1 is a HP xw8400, and the disks are connected to the first four
SATA ports (the xw8400 has both SAS and SATA ports, of which I use the
SAS ports for the system disks).
On Server2, the disk controller used for the data disks is a LSI SAS
9211-8i, updated with the latest IT-mode firmware (also tested with the
original IR-mode firmware)
The output of the 'format' command on Server2 is:
AVAILABLE DISK SELECTIONS:
0. c2t0d0 <ATA-OCZ-VERTEX3-2.11-55.90GB>
1. c2t1d0 <ATA-OCZ-VERTEX3-2.11-55.90GB>

6. c7t5000C50044E0F611d0 <ATA-ST3000DM001-9YN1-CC46-2.73TB>
Note that this is what it looks like now, not at the time I sent the
question. The difference is that I have set up three other disks (items
4-6) on the new server, and are currently transferring the contents from
Server1 to this one using zfs send/receive.
I will probably be able to reconnect the correct disks to the Server2
tomorrow when the data has been transferred to the new disks (problem
'solved' at that moment), if there is anything else that I can do to try
to solve it the 'right' way.
On the HP, on a reboot, I was reminded that the 3TB disks were displayed
as 800GB-something by the BIOS (although correctly identified by
OpenIndiana and ZFS). This could be a part of the problem with the
ability to export/import the pool.
It may be possible that on one controller disks are used
"natively" while on another they are attached as a JBOD
or a set of RAID0 disks (so the controller's logic or its
expected layout intervenes), as recently discussed on-list?

Server 1 (old)
The zpool consists of three disks in a raidz1 configuration:

c4d1 ONLINE 0 0 0

Server 2 (new)
I have attached the disks on the new server in the same order (which
shouldn't matter as ZFS should locate the disks anyway)
zpool import gives:
