CHAPTER 9—MODE SELECT (15h) Assigning Element Addresses An element is a way of classifying various components in the library. Element addresses reference specific physical locations in the library. All of the libraries contains these element types: Cartridge loader (medium transport) element Cartridge cells (storage) elements I/E port (import/export) elements Tape drive (data transfer) elements Each element requires an address so that it can be identified during a SCSI command operation.
PAGE 101
WHAT YOU SEND TO THE LIBRARY ! For the starting element addresses, you can specify any 16-bit Important binary number, with the following conditions: Element addresses must not overlap. Addresses within each type of element must be consecutive. The highest address you can assign for the first storage element is: Magnum 224 or T24–FFE8h (1111111111101000b). This causes the last storage element to be numbered 0FFFFh (1111111111111111b) StorageLoader 2U–FFECh (1111111111101100b).

CHAPTER 23—SEND VOLUME TAG (B6h) Notes: Refer to Table 23-1 for a description of each of these errors. In a multi-initiator environment, you should reserve the entire library using the RESERVE (16h or 56h) command before you use the SEND VOLUME TAG command. Do not issue the RELEASE (17h or 57h) command until after you have successfully obtained data with the REQUEST VOLUME ELEMENT ADDRESS command. You should issue the commands in the following order: 1. 2. 3. 4.

SEND VOLUME TAG PARAMETER LIST Starting Element Address – Byte 02 and 03 This field specifies the minimum element address at which to start the search for volume tag information that matches the template in the parameter list (see below). Only elements with addresses greater than or equal to the Starting Element Address are searched. Note: The Starting Element Address must be 0 or a valid element address for the library, but does not have to be an address of the type requested in the Element Type Code.

The library processes this command when it is executing the flash EEPROM code or when it is executing the ROM boot code.
PAGE 228
CHAPTER 25—WRITE BUFFER (3Bh) Be sure to heed the following cautions when issuing the WRITE BUFFER command to update the microcode stored in the library’s flash EEPROM. Caution The WRITE BUFFER command allows you to load new microcode over the SCSI bus into the library’s flash EEPROM. It is not intended to be used for testing library functionality (that is, do not issue this command unless you are actually loading new microcode). Do not load microcode from one model of library into another.

WHAT YOU SEND TO THE LIBRARY 25.2 WHAT YOU SEND TO THE LIBRARY Mode – Byte 01, Bits 2 through 0 The Mode field determines the type of operation to be performed. The library performs the following operations: 010b Write data into Read/Write buffer 100b Write microcode to buffer but do not save it to EEPROM 101b Write microcode to buffer and save entire buffer to EEPROM Buffer ID – Byte 02 Valid Buffer ID values are 00h, 01h, and 02h for Mode 010b, write data to Read/Write Buffer.

CHAPTER 25—WRITE BUFFER (3Bh) 25.4 COMMAND STATUS The library returns a status byte after processing the WRITE BUFFER command. This section describes when each type of status byte might be returned. Good The library returns Good status when it is able to process the command without errors. Busy Busy status indicates that the library is temporarily unable to accept a command from this initiator. The initiator may retry the command later.

A ERROR CODES This appendix describes the errors reported by the library. The library uses two methods for reporting error conditions: Errors that occur only when the library is being operated from the operator panel (Sequential mode), or when the library is performing diagnostics, only appear on the LCD and are not reported by the REQUEST SENSE command. If the library is operating in Random mode, errors are reported over the SCSI bus. Some of these errors also appear on the LCD, others do not.
