1.8.5 Oracle Automatic Storage Management (ASM) Enhancements

The log format for Oracle ASMLib that is used to manage Oracle ASM devices dedicated to Oracle Databases has been updated to include timestamps of the activities that are logged to /var/log/oracleasm.

The oracleasm command is improved for the scandisks operation so that it is able scan devices that are not directly available under /dev, but could be available within subdirectories within /dev. You can configure additional directories to be scanned during the scandisks operation by setting the Directories to scan option when using the interactive configuration tool, as shown in the following example:

# oracleasm configure -I
Configuring the Oracle ASM library driver.
...
The next two configuration options take substrings to match device names.
The substring "sd" (without the quotes), for example, matches "sda", "sdb",
etc.  You may enter more than one substring pattern, separated by spaces.
The special string "none" (again, without the quotes) will clear the value.

Device order to scan for ASM disks []:
Devices to exclude from scanning []: dm
Directories to scan []: /dev/mapper/
