Error Message

# /usr/lib/vxvm/bin/vxdmpraw enable oracle dba 755 emc_clariion0_252
  
VxVM vxdmpraw ERROR V-5-2-6158
                
Device ownership for the device 'emc_clariion0_252' is already set.
Please use vxdmpraw disable to remove ownership for
this device and then execute vxdmpraw enable with new 
​ownership details.

This is due to a bug in the VxVM code and the fix has been identified.

The /etc/vx/.vxdmprawdev file keeps track of the user/group ownership and permissions set for the ASM disks and since this file still exists, the following two workarounds will restore these values on the ASM disks.

Workaround #1:

# rm -rf /dev/vx/rdmp/*                                  
# rm -rf dev/vx/dmp/*                                 
# vxdctl enable

so for the emc_clariion0_252 ASM disk this workaround would have involved running:

# rm -rf /dev/vx/rdmp/emc_clariion0_252*
# rm -rf /dev/vx/dmp/emc_clariion0_252*
# vxdctl enable

Workaround #2:

# /usr/lib/vxvm/bin/vxdmpraw disable
# /usr/lib/vxvm/bin/vxdmpraw enable

so for the  emc_clariion0_252 ASM disk, the following commands would have been needed:

# /usr/lib/vxvm/bin/vxdmpraw disable oracle dba 755 emc_clariion0_252
# /usr/lib/vxvm/bin/vxdmpraw enable oracle dba 755 emc_clariion0_252


Additionally two hotfixes have been created for this - one for VxVM 6.1.1 on Solaris 10 sparc and one for VxVM 6.2.1 on Solaris 10 sparc.

If either of these hotfixes are required, please contact Veritas Support.

These fixes will be included in the next GA patches for the 6.1.1 and 6.2.1 on Solaris 10 sparc, but these GA patches have yet to be planned.

 

On a SFHA 6.1 and 6.2 cluster both running on Solaris 10 sparc, the Oracle databases were configured to run on ASM disks. However when running the 'vxddladm assign names' command as part of the device tree refresh activity when doing lun removal/addition activities, the user/group ownership and permissions for the ASM disks were being lost which resulted in a service interruption on the Oracle databases.

For example in the case of the emc_clariion0_252 ASM disk:

# /usr/lib/vxvm/bin/vxdmpraw enable oracle dba 755 emc_clariion0_252
  VxVM vxdmpraw INFO V-5-2-6157
                Device enabled : emc_clariion0_252
  VxVM vxdmpraw INFO V-5-2-6155
                Please set ASM_DISKSTRING to '/dev/vx/rdmp/*' or '/dev/vx/dmp/*'
                for Oracle ASM to work on DMP devices.

However after running the 'vxddladm assign names' command, the settings for the emc_clariion0_252 ASM disk were lost.
