In this post I am going to explore deleting a storage snapshot of an Oracle 19c RAC database created on a Dell PowerMax storage array.

This post is a companion to the video Dell PowerMax – Refresh a storage snapshot of Oracle RAC database. and a follow on from the blog post Create a storage snapshot of an Oracle 19c RAC database using ASM diskgroups with Dell PowerMax.

This blog post assumes some basic knowledge of PowerMax storage concepts. If you need a basic introduction please check out my PowerMax basics video.

These examples will use the Solutions Enabler command line method of managing the PowerMax, unlike the video which uses the Unisphere graphical interface.

ASM Filter Drivers – disks not filtering on reboot

Posted on by • Posted in ASM, ASMLib, Oracle • Tagged , , • Leave a comment

 

 

You’ve enabled ASM Filter Drivers, migrated your existing disks, and then after you reboot you see this:

[oracle@oel6solo ~]$ asmcmd afd_lsdsk
--------------------------------------------------------------------------------
Label Filtering Path
================================================================================
DATA2 DISABLED /dev/sdc
DATA4 DISABLED /dev/sde
DATA3 DISABLED /dev/sdd
DATA1 DISABLED /dev/sdb

You check the ASM Filter Driver state and it says it is loaded and filtering:

[oracle@oel6solo ~]$ asmcmd afd_state
ASMCMD-9526: The AFD state is 'LOADED' and filtering is 'DEFAULT' on host 'oel6solo.comp-lab.sc'

There is one more step that much of the documenation is missing:

[oracle@oel6solo ~]$ $ORACLE_HOME/bin/asmcmd afd_filter -e

Now the ASM FD filtering will survive a reboot:

[oracle@oel6solo ~]$ asmcmd afd_lsdsk
--------------------------------------------------------------------------------
Label Filtering Path
================================================================================
DATA2 ENABLED /dev/sdc
DATA4 ENABLED /dev/sde
DATA3 ENABLED /dev/sdd
DATA1 ENABLED /dev/sdb
