Creating Attach Points with makedev
Installing Oracle Secure Backup on Linux or UNIX 2-15
In the following example, the attach point
/dev/obl8
is created for the ADIC
FastStor 2 library attached to
scsi2
having the target id
0
and lun
0
:
makedev
Enter logical unit number 0-31 [0]: 8
Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable
tape library [d]: l
Enter SCSI bus name:
scsi2
Enter SCSI target id 0-16777215: 0
Enter SCSI logica l unit number (lun) 0-7 [0]: 0
/dev/obt8 created
In this second example, the attach point
/dev/obl9
is created for the ADIC Scalar
24 library attached to
fsci0
having the target id
6423827
and lun
0:
makedev
Enter logical unit number 0-31 [0]:
9
Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable
tape library [d]: l
Enter SCSI bus name: fscsi0
Enter SCSI target id 0-16777215: 6423827
Enter SCSI logical unit number (lun) 0-7 [0]: 0
/dev/obl9 created
The
makedev
script creates the attach point, displaying messages indicating its
progress.
Identifying and Configuring AIX Devices in a Point-to-Point or FC-AL Configuration
In a point-to-point or FC-AL configuration, no tool is provided to help you determine
the SCSI ID and LUN. However, for IBM-supported devices in these configurations,
you can use the
lsattr
command.
To identify and configure AIX devices with lsattr and makedev:
1.
Log on as
root
.
You must have operating system privileges to access devices, which is often root
access, to run
lsattr
.
2.
Run
lsattr
for each SCSI and Fibre Channel adapter with tape devices to be
used by
Oracle Secure Backup
.
The following
lsattr
example displays the attribute names, current values,
descriptions, and user-settable flag values for the
rmt0
device:
user: lsattr -El rmt0
block_size 512 BLOCK size (0=variable length) True
delay 45 Set delay after a FAILED command True
density_set_1 0 DENSITY setting #1 True
density_set_2 0 DENSITY setting #2 True
extfm yes Use EXTENDED file marks True
location Location Label True
lun_id 0x1000000000000 Logical Unit Number ID False
mode yes Use DEVICE BUFFERS during writes True
node_name 0x1000006045175222 FC Node Name False
res_support no RESERVE/RELEASE support True
ret_error no RETURN error on tape change or reset True
rwtimeout 144 Set timeout for the READ or WRITE commandTrue
scsi_id 0x2 SCSI ID False
var_block_size 0 BLOCK SIZE for variable length support True
ww_name 0x2001006045175222 FC World Wide Name False
