User_AAWNDNov 23 2022 — edited Nov 23 2022

Hi all, i have dificulties with ASM disks
OS specifications:
NAME="Oracle Linux Server"
PRETTY_NAME="Oracle Linux Server 8.7"

I have one disk 17 TB /dev/sdc
I divided it into partitions:
/dev/sdc1 5.1 TB
/dev/sdc2 5.1 TB
/dev/sdc3 6.8 TB
Set apporpiate permissions to partitons:
chown oracle:oinstall /dev/sdc1
chown oracle:oinstall /dev/sdc2
chown oracle:oinstall /dev/sdc3
chmod 600 /dev/sdc1
chmod 600 /dev/sdc2
chmod 600 /dev/sdc3

But when running installation script as oracle user, i can see only /dev/sdc disk
слика_2022-11-23_124730546.pngWhen clicking on /dev/sdc getting message:
[INS-30543] Installer has detected that one or more of the selected disk(s) is of size larger than 2 terabyte(TB). Because of this, the Oracle Database compatibility level (COMPATIBLE.RDBMS attribute) of the diskgroup (DATA) will be set to 12.1. This means that, in order to use the diskgroup for data storage, the COMPATIBLE initialization parameter of the Oracle Database should be greater than or equal to 12.1.
And disk can only be used as external.
ls -ltrh /dev/sdc*
brw------- 1 oracle oinstall 8, 32 Nov 23 12:54 /dev/sdc
brw-rw---- 1 oracle oinstall 8, 35 Nov 23 12:54 /dev/sdc3
