Installing Oracle 10gR2 Cluster Ready Services (CRS) with MPIO

/dev/raw/raw1 8 33

/dev/raw/raw2 8 49

/dev/raw/raw3 8 65

/dev/raw/raw4 8 97

/dev/raw/raw5 8 113

On the other nodes run blockdev so the partition table are read again and created:

# blockdev --rereadpt /dev/sdc

# blockdev --rereadpt /dev/sdd

# blockdev --rereadpt /dev/sde

# blockdev --rereadpt /dev/sdg

# blockdev --rereadpt /dev/sdh

Double check on the other nodes that the minor numbers for the block devices match. The second

number in the example below, 8 in this case, is the minor number and 1 is the major number.

$ ll /dev/sdh1

brw-rw---- 1 root disk 8, 113 Oct 1 13:14 /dev/sdh1

Copy /etc/sysconfig/rawdevices to other nodes then restart it. You will see the created raw

devices in /dev/raw.

# /etc/rc5.d/S56rawdevices start

Assigning devices:

/dev/raw/raw1 --> 8 33

/dev/raw/raw1: bound to major 8, minor 33

/dev/raw/raw2 --> 8 49

/dev/raw/raw2: bound to major 8, minor 49

/dev/raw/raw3 --> 8 65

/dev/raw/raw3: bound to major 8, minor 65

/dev/raw/raw4 --> 8 97

/dev/raw/raw4: bound to major 8, minor 97

/dev/raw/raw5 --> 8 113

/dev/raw/raw5: bound to major 8, minor 113

done

Now check that the permissions are set for the Oracle installation.

# ll /dev/raw

total 0

crwxrwxrwx 1 oracle dba 162, 1 Oct 1 13:13 raw1

crwxrwxrwx 1 oracle dba 162, 2 Oct 1 13:13 raw2

crwxrwxrwx 1 oracle dba 162, 3 Oct 1 13:13 raw3

crwxrwxrwx 1 oracle dba 162, 4 Oct 1 13:13 raw4

crwxrwxrwx 1 oracle dba 162, 5 Oct 1 13:13 raw5

Now you can commence an Oracle Clusterware installation.

Note

If during the installation process, Oracle says the raw devices are busy, then Multipath

was left on in one of the nodes.

After the VIPCA portion of the Oracle CRS is complete, you need to comment out the raw devices you

created and copy /etc/sysconfig/rawdevices to the other nodes:

1 2 ... 96 97 98 99 100 101 102 103 104 105 106 ... 159 160
