I have seen tho note:
"How to Restore ASM Based OCR After Complete Loss of the CRS Diskgroup on Linux/Unix Systems (Doc ID 1062983.1)"

This note:
"APPLIES TO:
Oracle Database - Enterprise Edition - Version 11.2.0.1.0 and later"

In the step 5 the note said: "Create the CRS diskgroup via sqlplus" but i have a backup of ASM configurationdone whit:
asmcmd spbackup
asmcmd pwcopy
asmcmd md_backup

Should i recreate the disk group or recover this backup?

I think that the process for recover the ASM instance is:
Restoring pw:

pwcopy --asm /.../pw_asm.backup  +rac18_ocr/orapwASM

Restoring server parameter file:

spcopy -u /.../spfileCopyASM.ora dest

I can get dest from:
$ORACLE_HOME/gpnp/itauc4603a/profiles/peer/profile.xml
SPFile="+RAC18_OCR/rac-exp/ASMPARAMETERFILE/registry.253.1002277713"

Restore disk configuration:

md_restore –-full –G data –-silent /.../md_backup

Is this process correct for recover ASM instance?

if we modify this part, is the complete process correct for the 18C version?

Thans for your attention.
