n is an integer in the range 0—65,535 (bytes). The default value is 24,576.
udevtabsiz is the maximum size in bytes of the device table. This table maps device numbers (traditional logical unit numbers) to device names, so that ObjectScript code can open devices by number.
Changing This Parameter
On the page System Administration > Configuration > Additional Settings > Advanced Memory, in the udevtabsiz row, select Edit. Enter a number of bytes.
Instead of using the Management Portal, you can change udevtabsiz in the Config.configOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
