If you are trying to create an ASMLIB disk using an emcpower# partition and you get the next error:
ASM disk: asmtool: Device "/dev/emcpowera11" is not a partition [FAILED]
Then you will need to determinate if the emcpower# partition is valid.
解决步骤如下:
In order to confirm the emcpower# partition is valid:
1) Check if you can create a tablespace directly on the block partition:
[root@dbaasm ~]# cd /dev
[root@dbaasm dev]# ls -l emcpowerd1
brw-rw---- 1 root disk 3, 19 Apr 29 16:00 emcpowerd1
[root@dbaasm dev]# chmod 777 emcpowerd1
[root@dbaasm dev]# ls -l emcpowerd1
brwxrwxrwx 1 root disk 3, 19 Apr 29 16:00 emcpowerd1
[root@dbaasm dev]# exit

SQL> create tablespace test datafile '/dev/emcpowerd1' size 100M;
Tablespace created.
2) If so, then drop the previous tablespace.
3) Then check if a diskgroup can be created directly on the block partition:
Connect as root and execute:
# dd if=/dev/zero of='/dev/emcpowerb1' bs=8192 count=12800
Then connect as oracle, and then connect to the ASM instances and execute:
SQL> alter system set asm_diskstring = '/dev/emcpowerb1' scope=memory;
SQL> create diskgroup TEST external redundancy disk '/dev/emcpowerb1';
Diskgroup created.
4) If the tablespace and diskgroup can be create directly on the block partition then this could be a problem with ASMLIB configuration. Therefore you will need to check if the correct ASMLIB rpms were installed.
5) Alternatively, you can check if the problem is reproducible on another emcpower# partition or ask the SA to recreate the original one.
