Setup Step: MDM020

Run ioscan and insf to probe/install new disk devices.

Scan for new disk devices on the first cluster node (clunode1). In the following example, the storage used for this configuration is EVA / HSV200 based fibre storage and was already initialized.

iocan -fnC disk

insf -e

disk 175 0/2/0/0.1.10.0.0.0.2 sdisk CLAIMED DEVICE HP HSV200 /dev/dsk/c12t0d2 /dev/rdsk/c12t0d2

disk 178 0/2/0/0.1.10.0.0.0.5 sdisk CLAIMED DEVICE HP HSV200 /dev/dsk/c12t0d5 /dev/rdsk/c12t0d5

Setup Step: MDM030

Create file systems and mount points on the first cluster node.

The following commands create the LVM file systems and mount points for the MDM components. The database file system in this configuration has a size of 20 GB (/oracle/MDM), the file system for the MDM components (/export/home/mdmuser) has a size of 7GB.

NOTE: The file system/export/home/mdmuser will be used by all 3 MDM server components MDS, MDIS and MDSS.

clunode1:

mkdir /dev/vgmdmoradb mkdir /dev/vgmdmuser

mknod /dev/vgmdmoradb/group c 64 0x500000 mknod /dev/vgmdmuser/group c 64 0x530000 pvcreate /dev/rdsk/c12t0d2

pvcreate /dev/rdsk/c12t0d5

vgcreate /dev/vgmdmoradb /dev/dsk/c12t0d2 vgcreate /dev/vgmdmuser /dev/dsk/c12t0d5 lvcreate -L 20000 -n lvmdmoradb /dev/vgmdmoradb lvcreate -L 7000 -n lvmdmuser /dev/vgmdmuser

newfs -F vxfs -o largefiles /dev/vgmdmoradb/rlvmdmoradb newfs -F vxfs -o largefiles /dev/vgmdmuser/rlvmdmuser

Create the mount point for Oracle.

mkdir -p /oracle/MDM

Create NFS export/import mount points for the /home/mdmuser home directory. The directory

/export/home/mdmuser is the NFS server ( NFS export) mount point, /home/mdmuser is the NFS client (NFS import) mount point.

mkdir -p /export/home/mdmuser

mkdir -p /home/mdmuser

Create the mount point for the MDM binaries directory.
