Supported Scsi Commands Chapter 3. This command enables the initiator to get a quick response from a Read Element Status command that may follow, and is useful after a power failure, if tape medium has been changed by an operator, or if subsystem configuration has changed. The media changer can provide two categories of data in response to an inquiry command: Standard Inquiry Data and Vital Product Data.

Standard Inquiry Data contains basic data about the Medium Changer and Vital Product Data can comprise several pages of additional data. Set to 2.

This field depends on the library model.

Field descriptions: Peripheral Qualifier: A return value of 0 indicates that the specified LUN is supported in this device. This event log is maintained in the media changer internal NVRAM and is therefore resistant to power failures.

Byte Operation Code 4Ch Reserved The statistical information is divided over several pages. Byte Operation Code 4Dh Reserved The target returns the bytes specified by allocation length. Byte Reserved Page Code Page Length: The Page Length specifies the total number of event bytes, not including the four bytes for this header.

Page 28 TMC: No threshold supported, set to 0. The List Parameter field is set to zero for parameters that are counters and set to one for parameters that are not counters.

Library Pick There is a potential problem with the cartridge loader picking a cartridge Retry from a drive or slot. Remedial action is advised. Performance of data may be at risk. Number of This 4 byte unsigned counter specifies the number of Configuration Change Configuration Change entries in the trace buffer. It ranges between 1 and Mode Select Parameter List The Mode Select parameter list shown below, contains a 4-byte header, followed by an optional 8 byte block descriptor after which the Mode Select pages are specified.

Page Control Extension Page 0ah Parity: By means of this field the host can enable parity retires. Parity retries are by factory default enabled by the media changer. When cleared parity retries are disabled.

This bit should be set to zero. When this bit is set to one this indicates that the media changer shall disable all information exception operations, ignoring the MRIE field In this mode the initiator must the poll the Tape Alert log page. Number of Medium Transport Elements: By means of this field the host can specify the number of robotic cartridge handlers within the library.

The initiator cannot change this information. Page 42 Sequential or Random mode. This mode cannot be changed by means of this page, it can only be changed by means of the OCP.

When a mask bit is cleared the event data of the subsequent firmware module will be discarded. For documentation on the supported Mode Pages refer to the Mode Sense 6 command.

Byte Operation Code 5Ah Reserved Scope: See SPC-3 r Type: See SPC-3 r The command uses other service actions to manage and remove such reservations. It is also used to read out Vendor Specific settings. Byte Operation Code 3Ch Reserved Allocation Length: This field specifies the number of bytes that the initiator has allocated for returned data.

Note that the Read Element Status command can be issued with an Allocation Length specified as 8 bytes the length of the status page header to determine the Allocation Length required to transfer all of the element status data that become available as a result of the command. An ED bit value of zero indicates the element is enabled. The next table describes the values for the Medium Types. Unspecified Data Medium Cleaning Medium An InEnab bit of zero indicates that this element does not support export actions.

A CMC bit of zero indicates that exports are to the operator and imports are from the operator.
