mapCompressDatabase

Caution

Compressing the map database will cause device addresses to change unpredictably. Use this command only when no host systems are expecting devices to remain at their current addresses.

Occasionally, it may be necessary to eliminate inactive entries and reorder the active entries in the Persistent Device Map database. The mapCompressDatabase command removes entries for devices that are no longer present and reassigns existing device entries to new addresses. The devices will be assigned new addresses immediately and hosts must rescan for devices or be rebooted.

This may be required when a host system has a limited number of logical units that may be supported, and changing devices on the SNC 5100 has caused the logical unit numbers to increase beyond the host’s supported level.

When you run this command you will be given the option of also clearing the SFM access settings. Because devices will be assigned new addresses, clearing the SFMdatabase ensures that hosts will not have access to the wrong LUNs.

Accepting this option requires that the system administrator must reassign SFM access permissions between the hosts and LUNs.
