1.12 Extending Disk Space

The extend option is provided to avoid performing a SAVE and RESTORE of the database to extend disk space. Follow the steps below to extend the available disk space for the mvEnterprise database.

1.Create the new logical disk devices and add the device names to the config script. Precede new disk device names by a new level number.

For example, an existing machine contains two disk devices /dev/dskwwww and /dev/dskxxxx. If two new disk devices, /dev/dskyyyy and /dev/dskzzzz, are to be added without performing a SAVE and RESTORE of the database, the information reflected in the config file is:

2.Ensure that all users are logged off and that Phantoms and printers are inactive.

3.Perform a SHUTDOWN from mvEnterprise.

4.Run the mvEnterprise install program. Type: install -o-m-i

5.Flag the mvEnterprise database for disk space extension. Type:

./prodpick -l0 -e

where prodpick is the name of the mvEnterprise monitor program. The -eoption flags the coldstart procedure to add the new available disk space (frames) to the overflow table.
