Prev: Create ClusterInstall Grid Infrastructure (e)
- Prepare for GI install
- Install Grid Infrastructure
- Check Cluster Status After GI Install
- ASM Configuration
- From a VNC session, run the ASM Configuration Assistant:
[oracle@collabn1 ~] . oraenv ORACLE_SID = [oracle] ? +ASM1 The Oracle base has been set to /u01/app/oracle [oracle@collabn1 ~]$ asmca
- The asmca opens on the Disk Groups tab, showing the DATA diskgroup created by the installer. Click on Create.
- Enter FRA as the disk group name.
Choose external (none) redundancy.
Check one disk to create a 5Gb diskgroup.
- The diskgroup is being created.
- The diskgroup is created.
- Click on the Volumes tab, then on Create.
You may face an error message at this stage. This is related to the fact that you user newer version of Linux kernel that is not comparable with ACFS. At this stage a feasible solution is to ignore the error and do not implement the ACFS (skip next steps). You may want to come back to ACFS implementation later on.
EnterSHARED as the volume name.
Choose the diskgroup DATA.
The size will be irrelevant in our labs, so enter 1.
- The volume is created.
- Select the ASM Cluster File Systems tab.
- Select Cluster File System.
User Name: oracle
Group Name: dba
- To complete the filesystem creation, run this script as root.
[root@collabn1 ~]# /u01/app/oracle/cfgtoollogs/asmca/scripts/acfs_script.sh ACFS file system /shared is mounted on nodes collabn1 ACFS file system /shared is mounted on nodes collabn2
- Finally, the filesystem is mounted on both nodes.
