Missing Diskgroup in CRS – Adding Manually

Hello

While doing some setup, I have came across a diskgroup (OCRDG) missing in CRS registry, however the diskgroup is present in the ASM instance and showing mounted.

[root@oinfo12c-rac1 ~]# crsctl stat res -t

As you see the output shows nothing about OCRDG, Lets look at asmcmd, and the OCRDG is present.

ASMCMD> lsdg

Seems some permission issue, etc, do not want to spend much time on it. Just want to add it manually.

But hold there, srvctl does not have

srvctl add diskgroup

How to add it then?

We have crsctl commands which you can add resource, Trying my luck.

If you have a any other diskgroup present in the CRS as like mine (DATA diskgroup is there), Just copy and register it as like below

1) crsctl stat resource ora.DATA.dg -p > profile.txt

2) vi profile.txt
### Remove Name,Type from the file rest keep as is.

3) Add the resource
crsctl add resource ora.OCRDG.dg -type ora.diskgroup.type -file profile.txt

4) Check the status again

[root@oinfo12c-rac1 ~]# crsctl stat res -t

If you do not have any other diskgroup, try this

1. crsctl add resource ora.OCRDG.dg -type ora.diskgroup.type -attr ="ACL=owner:oracle:rwx,START_DEPENDENCIES=pullup:always(ora.asm) hard(ora.asm),VERSION=12.1.0.1.0"

This is should add the missing diskgroup.

Have fun.
