All, I've been reading through the forums and metalink looking for
this particular problem but haven't been able to find the answer. I
have 2 nodes (OEL 5) multipathed to our backend storage. Both nodes
are configured with asmlib and the CRS daemons are installed and
running great on them. The whole setup is 10g release 2.
Prior to disk creation, I set the ORACLEASM_SCANORDER in
/etc/sysconfig/oracleasm and added "multipath dm" to it. I even added
"sd" to ORACLEASM_SCANEXCLUDE so that all scans happen on the
multipath channel.
I then create the disk with the following (I have tested this from
both node1 and node2).
#service oracleasm createdisk TESTDATA /dev/dm-4
Scanning the asm disks on both nodes as root successfully shows the
TESTDATA asm disk (service oracleasm scandisks followed by service
oracleasm listdisks).
On node1, querying v$asm_disk shows TESTDATA provisioned and ready to
go. Node2 never shows it. I have added ORCL:* to the asm_diskstring
and bounced the instance on node2 but to no avail.
I have blown away the configuration, zeroed out the underlying
storage, and started fresh but I get the same results.
Here's the SQL output from node2.
SQL> show parameter asm
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups string
asm_diskstring string ORCL:*
asm_power_limit integer 1
SQL> select * from v$asm_disk;
no rows selected
SQL>
If I query /dev/oracleasm/disks, I do see the TESTDATA disk owned by
oracle:dba on both nodes.
Can anyone point me in a direction I haven't tried?
Thanks!
Brian
