5.1 About This Command

The INQUIRY command requests that information about the CTS’s

parameters be sent to the initiator. The CTS executes the INQUIRY

command whether a tape is loaded and whether it has been reserved

by another initiator.

The CTS will return inquiry data within 3 seconds of a power cycle or

when a Unit Attention condition exists. Issuing an INQUIRY

command does not clear a pending Unit Attention for the initiator.

5.2 Field Definitions

Byte 01, Bit 0 - EVPD

The Enable Vital Product Data bit indicates the type of inquiry data

being requested by the initiator, as follows:

0 – Return the standard Inquiry Data Table

1 – Return one of the Vital Product Data pages, based on the value

specified for the Page Code field (byte 02)

Byte 02 - Page Code

The Page Code field contains the page number of the Vital Product

Data page to be returned to the initiator for this INQUIRY command.

The CTS supports the following values for the Page Code:

00h – Supported Vital Product Data page

80h – Unit Serial Number page

If the EVPD bit (byte 1, bit 0) is set to 0, the Page Code must be 00h.
