SVM sees non-unique device IDs

Hello,
I am having a problem setting up a meta device using SVM on Solaris 9.
While trying to create a couple single slice concatenations, each using a
different (but model-identical) disk, the metainit command claims that the
second concatenation overlaps with the first. Eg:
# metainit d3 1 1 c1t3d0s0
d3: Concat/Stripe is setup
# metainit d4 1 1 c2t4d0s0
metainit: halifax: c2t4d0s0: overlaps with device in d3
The metastat command shows the first concat was created, but the device ID
for the disk is not right.
# metastat
d3: Concat/Stripe
Size: 143246394 blocks (68 GB)
Stripe 0:
Device Start Block Dbase Reloc
c1t3d0s0 0 No Yes
...
Device Relocation Information:
Device Reloc Device ID
c1t3d0 Yes id1,sd@w5000000000000000
If I reverse the order of the metainit commands, the d4 concat is created
with the c2t4d0 disk, however the device ID shown by metastat is identical
to that shown for the c1t3d0 disk.
I have tried running 'metadevadm -u' on the disks, but that changed
nothing.
The disks used here are Seagate model ST373455LC. They are housed in
external Sun enclosures. There are two other disks, mounted internally,
already in use by SVM which are identified correctly:
c0t1d0 Yes id1,sd@SSEAGATE_ST373307LC______3HZ06B450000732282SN
c0t0d0 Yes id1,sd@SSEAGATE_ST373307LC______3HZ04E8Q00007320FHV4
I'm wondering where I should look for how the SVM commands determine the
device ID, or if maybe there's a way to set or force the ID.
Thanks,
Johnathan
