Hi;
We have a two node Oracle 10g RAC for the Development (i.e. DEV1 , DEV2)and another two node 10g RAC for the Production. When, I was looking through the DEV Cluster; I found that there will be a need to add some more RAW disks to the existing ASM DISK Groups.
Below is the output of the ASMCMD -P and followed by the LSDG Command (I am only enclosing the needed columns) :
Usable_file_MB NAME
-------------- -------
256602 DWDATA/
126722 DWINDX/
91885 DWREDO/
The above is an Extended RAC Cluster. I would like to add more disk space for the DWREDO Disk Group.
Below is the output for the V$ASM_DISK :
----------------------------------------
DEV1 - FAILGROUP
----------------
DWDATA1
DWREDO1
EMCDATA2
EMCINDX1
GROUP_NUMBER DISK_NUMBER NAME FAILGROUP
------------ ----------- ------ -----------
2 0 DWDATA1 DWDATA1
3 0 DWREDO1 DWREDO1
2 1 EMCDATA2 EMCDATA2
6 0 EMCINDX1 EMCINDX1
DEV2 - FAILGROUP
----------------
DWDATA1
DWREDO1
EMCDATA2
EMCINDX1
GROUP_NUMBER DISK_NUMBER NAME FAILGROUP
------------ ----------- ------ -----------
2 0 DWDATA1 DWDATA1
3 0 DWREDO1 DWREDO1
2 1 EMCDATA2 EMCDATA2
6 0 EMCINDX1 EMCINDX1
Just in case, if I have to add some Raw Disks to the DWREDO
-----------------------------------------------------------
(ASM) Group :
-------------
ALTER DISKGROUP DWREDO ADD
failgroup DWREDO1 disk '/dev/rdsk/SDX01' name DWREDO1
failgroup DWREDO1 disk '/dev/rdsk/SDX02' name DWREDO1;
[The RAW Disks coming from two different disk arrays to facilitate the Extended RAC Scenario and this is setup as Normal Redundancy.].
I would like to know if the above syntax is correct ?
Many Thanks
