Two updates:
Oracle Support has responded rather quickly, so perhaps I may be able to get
an answer through those channels first, for a pleasant change. =)
Also, ASM on node1 mounted the disk fine, but node2 has the problem:
NODE1_SQL> select state,header_status,substr(name,1,12) Name,free_mb,
substr(path,1,16) PATH from v$asm_disk;
STATE HEADER_STATU NAME FREE_MB PATH
-------- ------------ ------------ ---------- ----------------
NORMAL PROVISIONED 0 ORCL:VOLUME2
NORMAL MEMBER VOLUME1 34766 ORCL:VOLUME1
NODE2_SQL> select state,header_status,substr(name,1,12) Name,free_mb,
substr(path,1,16) PATH from v$asm_disk;
STATE HEADER_STATU NAME FREE_MB PATH
-------- ------------ ------------ ---------- ----------------
NORMAL UNKNOWN 0 ORCL:VOLUME2
NORMAL UNKNOWN 0 ORCL:VOLUME1
It has been suggested that I try to drop and recreate the disks. I am
willing to try it (because this is a new install), but will that mess things
up for node1?

Oracle Support will eventually get around to it. =)
Hardware/software:
RHEL4 (Nanant) running on 2 Dell 2950's, gigabit nic
Stock Oracle 10.2.0.1 for clusterware and asm oracle home
CRS install went just dandy, including all of K Gopal's suggest cluvfy
steps. The ASM install was going nicely until I hit the DBCA, at which point
the ASM instance on node 2 could not start because it could not mount the
disks. After digging around and finding Varga's
blog<http://blogs.oracle.com/AlejandroVargas/newsItems/viewFullItem$126>,
I did some homework with my sysadmin and configured /etc/sysconfig/oracleasm
to exclude the scsi drivers from our linux multipath ( not EMC PowerPath)
scans. So, how do I get my ASM instance to mount the disks after solving
that little riddle? I am looking through K Gopal's book (and now we have
Julian Dyke's book as well); I am sure the answer is in there somewhere, but
if someone wants to give me a little hint as to what page, that would be
cool. *grin*
For those interested in nitty-gritty details, here is the current error:
SQL> ALTER DISKGROUP ALL MOUNT;

I have also looked at Metalink notes:
*391136.1
* *309815.1
**353423.1 - this one might be helpful, but since node1 appears to be ok,
I am not so sure about dropping the diskgroup
* 398622.1 - I saw a reference for this, but cannot find the note itself.
TIA. Hopefully, I am missing something obvious.
