1. Creation new diskgroup
[oracle]$ 

export ORACLE_HOME=/u01/app/19.0/grid
export ORACLE_HOME=+ASM
$ORACLE_HOME/bin/sqlplus -s /nolog << EOF
connect /as sysasm
create diskgroup DATA external redundancy disk 'AFD:DATA01'  ATTRIBUTE 'compatible.asm' = '19.0','compatible.rdbms' = '19.0','compatible.advm' = '19.0','au_size' = '1M';

exit;
EOF

-- checking disks

[oracle]$ asmcmd lsdsk

-- note

ALTER DISKGROUP DATA SET ATTRIBUTE 'compatible.asm' = '19.0';

ALTER DISKGROUP DATA SET ATTRIBUTE 'compatible.rdbms' = '19.0';

ALTER DISKGROUP DATA SET ATTRIBUTE 'compatible.advm' = '19.0';

2. Creation new volumes
[oracle]$ 

export ORACLE_HOME=/u01/app/19.0/grid
export ORACLE_HOME=+ASM
asmcmd volcreate -G DATA -s 80g --column 8 oradata
asmcmd volcreate -G DATA -s 10g --column 8 oralog

3. Enable volumes

[oracle]$ 

asmcmd volenable --all
-- info about
asmcmd volinfo --all

4. Creation file system
[root]# 

mkfs -t acfs /dev/asm/oradata-360
mkfs -t acfs /dev/asm/oralog-360

5. Mounting new path
[root]# 

mkdir -p /u02/oradata/bank /u02/fra
mount -t acfs /dev/asm/oradata-360 /u02/oradata/bank

mount -t acfs /dev/asm/oralog-360 /u02/fra
chown -R oracle:oinstall /u02/
