If the external storage devices do not appear in the /proc/partitions file:
1
Stop the PowerPath service on all nodes by typing:
service naviagent stop
service PowerPath stop
2
Reload the HBA driver on all nodes to synchronize the kernel's partition tables on all nodes by typing:
• For QLogic HBAs:
rmmod qla2300
modprobe qla2300
• For Emulex HBAs:
rmmod lpfc
modprobe lpfc
3 Restart the PowerPath service on all nodes by typing:
service PowerPath start
service naviagent start
4
Confirm that all nodes see the external storage devices by typing:
more /proc/partitions
Configuring Shared Storage for CRS
This section provides instructions for configuring the shared storage for Cluster Ready Services (CRS).
The votingdisk and Oracle Cluster Registry (OCR) files can be created on a shared OCFS partition or
raw devices. To create an OCFS partition for the CRS files, see "Configuring Shared Storage Using OCFS".
To configure a shared storage with ASM, perform the following steps:
1
On the first node, create three partitions on an external storage device with fdisk :
Ty p e
fdisk /dev/emcpowerx and create three partitions of 150 MB each for the Cluster
Repository, voting disk, and the Oracle system parameter file.
2 Verify the new partitions by typing:
more /proc/partitions
If the new partitions do not appear in the /proc/partitions file, type:
sfdisk -R /dev/<device name>
