Get with your SAs and ask them to track the device names (/dev/dsk/xxxxx or /dev/hdiskXXXX) from file systems (logical volumes), all the way to the disk array. You will find your problem.
- Kirti -----Original Message----- Sent: Thursday, February 20, 2003 4:43 PM To: Multiple recipients of list ORACLE-L We actually had lengthy discussions with our SAs and convinced them that we need different mountpoints on different disks. We have our SA's guarantee that no physical disk is used by the two mountpoints... Will try to get a "sar -d" output from them..

Note that I enclosed the 'disk' above within quotes. Different filesystems and mount points does not necessarily mean much in these days where a single storage array may be shared among multiple servers. As long as you are not using JBODs, i.e. you are on a SAN/NAS, there is no physical guarantee that the disks are where they purport to be. Can your SA verify that these 'disks' are actually different? A 'sar -d' during that period may reveal some interesting results.
