TABLE E-9 Advanced Device Properties Screen Field Descriptions
Field Description
Maximum INT 13
devices for this
adapter
The maximum number of devices attached to the adapter for which
to install a pre-OS I/O interface. The specified number of devices in
the adapter’s device scan order list will have an I/O interface
installed. (An installed I/O interface is defined as INT 13H.) X86
platforms allow a maximum of 24 INT 13h devices per system.
Therefore, fewer than the specified number of INT 13h devices may
be installed. The default for X86 is 24 devices, with a range of 0-24
allowed.
Maximum target
device spinups
The maximum number of targets that can simultaneously spin up.
The IOC must delay by the time indicated in the spin-up delay field
before it starts spin-up of the next set of targets. A value of 0 in this
field is treated the same as a value of 1.
IO Timeout for
Block Devices
The time, in seconds, (0-999, 0 = no-time-out) that the host uses to
timeout I/Os for the following devices with nonremovable media:
• SCSI Device Type 00h - Direct Access
• SCSI Device Type 04h - Write Once
• SCSI Device Type 07h - Optical
• SCSI Device Type 0Eh - Simplified Direct Access
IO Timeout for
Block Devices
(Removable)
The time, in seconds, (0-999, 0 = no-timeout) that the host uses to
timeout I/Os for the following devices with removable media:
• SCSI Device Type 00h - Direct Access
• SCSI Device Type 04h - Write Once
• SCSI Device Type 05h - CD-ROM
• SCSI Device Type 07h - Optical
• SCSI Device Type 0Eh - Simplified Direct Access
IO Timeout for
Sequential Devices
The time, in seconds, (0-999, 0 = no-timeout) that the host uses to
timeout I/Os for the following devices:
• SCSI Device Type 01h - Sequential Access
IO Timeout for
Other Devices
The time, in seconds, (0-999, 0 = no-timeout) that the host uses to
timeout I/Os for devices other than the following:
• SCSI Device Type 00h - Direct Access
• SCSI Device Type 01h - Sequential Access
• SCSI Device Type 04h - Write Once
• SCSI Device Type 05h - CD-ROM
• SCSI Device Type 07h - Optical
• SCSI Device Type 0Eh - Simplified Direct Access
