N=0…7

Type

Value

Specifies size of the tape image and (optionally) size of "early-warning" area at the end of tape image.

Syntax:

"<image-size>[, <early-warning-zone-size>]"

where:

  • <image-size> is the tape size in MB

  • <early-warning-zone-size> is the size (in KB) of space remaining on the tape when a warning to the OS is issued. If omitted, 64K is assumed.

Parameter

disconnect_timeout[N]

N=0…7

TypeNumeric
Value

Sets logical unit disconnect timeout. This parameter helps if a connected SCSI device performs a given SCSI command for a very long time.

The default value depends on the type of the SCSI device attached. For example for a disk it is 10 seconds, for a tape - an hour. If the type of the device is not known the timeout is 1 hour.

Example (the timeout is 48 days):

set

pka_0

disconnect_timeout[1]

=

0x400000

(info) 0x400000 (hex) = 4194304 (dec) ~= 60 x 60 x 24 x 48 (days)
