The bare device created in Aix is the logical volume for Oracle in Aix

A bare device created in Aix is a logical volume in Aix

The creation method is as follows:

Syntax: Mklv-t raw-y [Lvname] [vgname] [LPs]

For example, to create a bare device required by Oracle:

Mklv-t raw-y Lv_sysaux Datavg 3

Mklv-t raw-y lv_systems aux datavg 3

Mklv-t raw-y LV_CTL1 Datavg 1

Mklv-t raw-y LV_CTL2 Datavg 1

Mklv-t raw-y lv_redo1 Datavg 1

Mklv-t raw-y Lv_redo2 Datavg 1

Mklv-t raw-y lv_undotbs01 Datavg 3

Mklv-t raw-y LV_TEMP01 Datavg 2

Mklv-t raw-y lv_users01 datavg2

Mklv-t raw-y LV_SPFILEORCL Datavg 1

Mklv-t raw-y LV_PWDORCL Datavg 1

# ls-alt/dev/lv_* will find the block device corresponding to all the logical volumes just created

# ls-alt/dev/rlv_* will find the character device corresponding to all the logical volumes just created

Set all character devices as Oracle:oinstall owners

# chown Oracle:oinstall/dev/rlv_*

Set all character device permissions to 700

chmod 700/dev/rlv_*

Use ls-alt/dev/rlv_* to see if the changes are correct.

Note: There are some problems with creating a logical volume using the above method, which will skip the first block of data (called offset) when using such a logical volume Oralce. You can use the-t o parameter to mask offsets on AIX.

Syntax: mklv-y [lvname]-T O [vgname] [PPs]

For example:

Mklv-t o-y Lv_systems Datavg 3
