Commands

6-00020-02

The

mapRebuildDatabase

command deletes the current database. When the

SNC 5100 is next booted, the devices found will be assigned new addresses.

When you run this command you will be given the option of also clearing the
SFMaccess 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.

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.

SN60023 > mapRebuildDatabase

This command will clear the Persistent Device Map.

Existing SFM Access Settings may become invalid and

should be cleared because LUN assignments may change!

These changes will take effect when the SNC 5100 is rebooted.

mapShowDatabase

The SNC 5100 maintains a database of attached devices, to insure that each
time a host attaches to it, the target devices are seen at a consistent address. The
database will list not only the devices presently connected, but also devices that
have previously been connected. If a previously attached device is later
reattached, it will be assigned back to its previous address. Use the

mapShowDatabase

command to display the persistent device map table.
