Chapter 1. Introduction

| | |

The IBM Ultrium Internal Tape Drive Models T200 and T200F and the IBM 3580 Ultrium Tape Drive are high-performance, high-capacity data-storage devices that connect to and provide additional storage for supported servers.

The Model T200 uses a Small Computer Systems Interface (SCSI) and the Model T200F uses a Fibre Channel interface.

| |

The 3580 Ultrium Tape Drive contains the Ultrium Tape Drive Model T200 (the SCSI drive).

Figure 1 shows the IBM 3580 Ultrium Tape Drive.

Figure 1. The IBM 3580 Ultrium Tape Drive

a67s0001

Designed to perform unattended backups as well as to retrieve and archive files, the Ultrium Internal Tape Drives feature:

v Native storage capacity of 100 GB per cartridge (200 GB at 2:1 compression) v Native sustained data transfer rate of 15 MB per second (30 MB at 2:1

compression)

v RS-422 interface for enhanced performance in automated tape libraries.

| | |

| | | |

The Ultrium Internal Tape Drive Model T200 uses an Ultra2 SCSI Low Voltage Differential/Single Ended (LVD/SE) interface. It features a burst data transfer rate of 80 MB per second.

The Ultrium Internal Tape Drive Model T200F uses a Fibre Channel interface with a SC-Duplex, multimode optical connector and SCSI protocol. It features a burst data transfer rate of 100 MB per second and can attach to Storage Area Network (SAN) components.

The 3580 Ultrium Tape Drive is available in two models. The models vary according to the type of SCSI interface that each uses to communicate with the server:

v Model L11 uses the Ultra2, Low Voltage Differential/Single Ended (LVD/SE)

interface. It has a burst data transfer rate of 80 MB per second.

v Model H11 uses the Ultra, High Voltage Differential (HVD) interface. It has a

burst data transfer rate of 40 MB per second.

1. 1 GB = one gigabyte or 1 000 000 000 bytes

2. 1 MB = one megabyte or 1 000 000 bytes

If the Long bit is set, EOD is written at the current position. A Data Set Separators pattern is written from EOD to the end of the medium to overwrite any data currently on the tape. If the Long bit is clear, then an EOD is written at the current position and marks it as end of data.

If the Immediate (Immed) flag is set to 1, then the drive validates the command and waits for any previous command from any server to complete, including any immediate commands that are currently being processed. It also waits for any buffered data to be flushed to tape. It then reports a deferred error for any preceding command or buffered data, if appropriate. If there is no deferred error, the drive reports Good status and initiates the command. If the Immediate (Immed) flag is set to 0, status is not returned until after the command has completed.

After the command is successfully completed, the drive is positioned immediately before End Of Data (not End Of Tape).

The INQUIRY command instructs the drive to return data about itself to the initiator. If the Enable Vital Product Data (EVPD) flag is clear and the Page Code is 0,

standard Inquiry Data is returned. If the Enable Vital Product Data (EVPD) flag is set and the Page Code is 0, the

Supported Vital Product Data Pages page is returned. If the Enable Vital Product Data (EVPD) flag is set, if the Page Code is not 0, and if

there is a vendor-defined Inquiry data page that corresponds to that page code, then that page is returned. Supported pages are 03h, 80h, 83h, C0h, and D0h. The contents of pages 03h and D0h are not specified in this document.

If the preceding conditions do not apply, Check Condition status is returned. The Sense Key is set to Illegal Request (5) and the ASC/ASCQ is set to Invalid Field in CDB (2400).

Values for the Adr16 bit are 1 (for SCSI) or 0 (for Fibre Channel). Values for the WBs16 bit are 1 (for SCSI) or 0 (for Fibre Channel). Values for the Sync bit are 1 (for SCSI) or 0 (for Fibre Channel). The Vendor Identification returns IBM in ASCII with trailing blanks. Product

Identification and Product Revision Level are set to vendor-specific strings. The Vendor Identification returns IBM in ASCII with trailing blanks. The Product Identification returns ULT3580-TD1 in ASCII with trailing blanks. The Product Revision Level has four values: Y represents year, M represents month,

D represents day, and V is a suffix. For V, values of 0 through 9 and A through Z are valid; a value of 0 is designated as earliest or least significant, and Z is designated as most significant.

Identification Descriptor

The device Identification Descriptor is returned by both the Parallel SCSI- and Fibre-Channel-attached devices.

The Code Set field is 2, indicating the Identification Descriptor contains only ASCII data.

This device supports Identifier Type of 1. In this case, the Identification Descriptor is the Vendor ID followed by the Product Identification field from the standard inquiry data and the Serial Number field from the Serial Number Inquiry Page (see “Unit Serial Number Page” on page 10).

The Parallel SCSI drive reports only the single Identification descriptor of Identifier Type 1.

The Fibre Channel Identification descriptor is returned only on Fibre-Channelattached devices. The format is given in Table 10.

each of the components of the drive. This device supports only one Drive Component Revision Levels Page (Page C0h). The values returned by the device in this page are unique to the vendor and are not specified in this document.

This page contains four null-terminated ASCII strings. The Component entry has a twelve-character entry to identify the component that the revision is for. The Version entry has a seven-character version code, with a three-digit major revision number, a period, and a three-digit minor version number. The date entry has the date of the version, in year-first order. The Variant entry has a variant identifier, indicating the version of the product.

If the Load flag is set and there is a tape in the drive, it is positioned to BOM. If the Load flag is set and there is no tape in the drive, Check Condition status is returned. The Sense Key is set to Not Ready (2) and the ASC/ASCQ is set to Parameter Medium Not Present (3A00).

If the Load flag is clear, there is a tape in the drive, and medium removal prevention has not been set, then the tape is unloaded and ejected. If the Load flag is clear, there is a tape in the drive, and medium removal prevention has been set, then Check Condition status is returned. The Sense Key is set to Illegal Request (5) and the ASC/ASCQ is set to Medium Removal Prevented (5302).

If the Load flag is clear and the tape is in the ejected position, the command is presented with Check Condition status and associated sense data of 2/0402 (Not Ready, Initialization Required). If the Load flag is clear and there is no cartridge present, the command is presented with Check Condition status and associated data of 2/3A00 (Not Ready, Medium Not Present).

The End Of Tape (EOT) and Retension (Reten) flags are not supported and should be set to 0.

LOCATE

The LOCATE command causes the logical position on tape to be set to the value indicated by the Block Address field. The value indicates the total number of records and marks between BOM and the desired logical position. A value of 0 causes the tape to be positioned at BOM.

Parameter List Length

The LOG SELECT command causes log data on the drive to be reset to its default value or to be set to an initiator-specific value.

If the Parameter Code Reset (PCR) flag is set, the Parameter List Length is 0, and the Page Control (PC) field is 01b or 11b, then all the logs on the drive that can be reset are reset to their default values.

If the Parameter Code Reset (PCR) flag is set, the Parameter List Length is 0, and the Page Control (PC) field is 00b or 10b, then no action is taken and Good status is returned.

If the Parameter Code Reset (PCR) flag is clear, the Parameter List Length is not 0, and the Page Control (PC) field is 01b or 11b, then data is sent from the server and is written to the indicated logs, provided those logs are writable.

If the preceding conditions do not apply, Check Condition status is returned. The Sense Key is set to Illegal Request and the ASC/ASCQ is set to Invalid Field in CDB (2400).

The Save Page (SP) flag is not supported and must be set to 0.
