1.148 SCAN ALL

Purpose

Use at the server console to scan all LUNs of all SCSI adapters in the server or all LUNs associated with a designated SCSI adapter.

IMPORTANT:SCAN ALL forces a scan and takes an order of magnitude longer to execute than SCAN FOR NEW DEVICES does. SCAN ALL should be used only when you know that there is an undetected device on a LUN other than LUN0.

Syntax


SCAN ALL An

Parameter	Use to
(no parameter)	Scan all LUNs of all SCSI adapters in the server.
An	Specify the SCSI adapter you want to scan. Find the An number by entering the LIST STORAGE ADAPTERS command at the console. The An number is enclosed in square brackets to the left of the storage adapter name, for example: [V312-A0] ADAPTEC PCI Host Adapter Module To scan all LUNs associated with the adapter in the example, you would enter: SCAN ALL A0

Parameter

Use to

(no parameter)

Scan all LUNs of all SCSI adapters in the server.

Specify the SCSI adapter you want to scan.

Find the An number by entering the LIST STORAGE ADAPTERS command at the console. The An number is enclosed in square brackets to the left of the storage adapter name, for example:

[V312-A0] ADAPTEC PCI Host Adapter Module

To scan all LUNs associated with the adapter in the example, you would enter:

SCAN ALL A0

Using SCAN ALL

Several utilities perform much the same operation, but they each differ in some respects.

LIST STORAGE ADAPTERS displays a list of registered storage adapters and the devices they drive. The information is read from the Media Manager database.
LIST DEVICES forces a scan for devices , displays the return list of storage devices, and registers any new devices with the Media Manager database. This command does not simply read the database.
SCAN FOR NEW DEVICES forces a scan on LUN0 of SCSI adapters and registers new devices with the Media Manager so that they are available to the operating system. This command scans only SCSI devices.
