SCSI REFERENCE 1014826

CHAPTER 9—MODE SELECT (15h)

 The MaxStorAddr field is directly related to the Slot Count option available from

the library’s operator panel. When this field is set, the library only uses the

number of cartridge cells specified as storage elements. The unused cells are not

available for use as addressable storage elements. The number of cells can be

set, cleared, or viewed using the operator panel or by issuing a MODE SELECT

command with this field set to the desired number of cells.

 If both the Fixed Cleaning Cell and Auto-Clean flags are set to 1 on the Cleaning

Configuration Page (see page 9-13), the cleaning cell, indicated by the

MaxStorAddr field is used for the cleaning cartridge and is not accessible using

SCSI commands.

 The library ignores the MaxStorAddr field if the MaxStor bit is set to 0. If the

MaxStorAddr field is set to 24 (18h), 20 (14h), or 48 (30h), the library responds

as if the MaxStor bit is set to 0.

 Changes to the MaxStorAddr field do not take affect until the library is reset.

DisIEP – Byte 05, Bit 6 (Disable I/E Port 1)

This field specifies whether the I/E Port is enabled or disabled.

 Magnum 224, T24, or SL 2U—The library has only one I/E Port (I/E Port 1).

 Enabled—Enabling the I/E port consumes the first storage slot. If the I/E

port is enabled, storage slots are numbered 01h-17h starting with the

storage slot beneath the I/E port.

 Disabled—If the I/E port is disabled, cell 71h does not exist and you

have 24 storage slots.

 Magnum 448—The Magnum 448 LTO Library has two physical I/E Ports (I/E

Port 1, which is the bottom element, and I/E Port 2, which is the top element).

See DisIEP2 – Byte 05, Bit 6 (Disable I/E Port 2) for information about the

second/top I/E port.

 Enabled—Enabling the bottom I/E port consumes the first storage slot. If

this I/E port is enabled, storage slots are numbered 01h-30h starting with

the storage slot beneath the I/E port.

 Disabled—If the bottom I/E port is disabled, cell 71h does not exist and

you have 48 storage slots.

For additional information, see:

0 I/E Port is enabled for use

1 I/E Port is disabled, the slot becomes a storage cell

0 I/E Port is enabled for use
