Hi all,
really interesting thing I have encountered . So :

root@host4 # uname -a
SunOS host4 5.9 Generic_122300-31 sun4u sparc SUNW,Sun-Fire-880
root@host4 # scinstall -p
3.2

latest recommended patches applied ..all SUN cluster patches applied.

SUN cluster software installed without any issue.
all needed resource types installed:

root@host4 # clrt list
SUNW.LogicalHostname:2
SUNW.SharedAddress:2
SUNW.gds:6
SUNW.HAStoragePlus:4

so I created simply one resource group ..

root@host4 # clrg create data-rg

and then created logicalhostname:

root@host4 # clrslh create -g data-rg -h datalh datalh-rs

and simply created SUNW.HAStorkagePlus:

root@host4 # clrs create -g data-rg -t SUNW.HAStoragePlus -p AffinityOn=TRUE -p FilesystemMountPoints=/data1,/data2 hasp-rs

then simply tried enable resource group with it's resources ..
Everything fine .. it started up .. got logicalhostname .. and then mounted /data1 and /data2 ..
here I create directory in /data1
root@host4 # mkdir /data1/test
root@host4 # cd /data1/test
root@host4 # mkfile 5m file1
root@host4 # mkfile 10m file2
root@host4 #chown -R mysql:mysql /data1/test

I gave all included files owner as mysql ..

then I'm testing it .. failed it over to second node .. it started on second node succesfully .. but here the problem is .. I look in /data1 and so that permissions of that directory "test" and files that I ceated changed ..

root@host3 # cd /data1
root@host3 # ls -al test
total 30756
drwxr-xr-x 2 60003 mysql 512 Dec 16 14:58 .
drwxr-xr-x 4 root root 512 Dec 16 14:58 ..
-rw------T 1 60003 mysql 5242880 Dec 16 14:58 file1
-rw------T 1 60003 mysql 10485760 Dec 16 14:58 file2

.. from where does it take "60003" ?!!!!!

If I fail it over again to forst node it is ok with it's permissions:

root@host4 # ls -al
total 30756
drwxr-xr-x 2 mysql mysql 512 Dec 16 13:49 .
drwxr-xr-x 5 root root 512 Dec 16 13:47 ..
-rw------T 1 mysql mysql 5242880 Dec 16 13:49 file1
-rw------T 1 mysql mysql 10485760 Dec 16 13:49 file2


...

You do have a mysql user on the node with the same uid as the node the file was created on ?

Thank you for reply.
I have of course .. I set up all necessary preinstallation configuration ..
But I recognised that when I enable resourse that was registered for mysql it works on active node and besides this it chages uid of mysql user on other node .. I don't know maybe it is bug .. so I manually updated /etc/passwd file on standby node .. modified it for user mysql .. and then tried failover .. it works )))

Anyway I couldn't find that it's bug on sunsolve ..

Thanks in advance ..
Good luck
