Conﬁguring Tape Drives

Conﬁguring HP-UX for a Tape Drive

d. Save the old system ﬁle by moving it. Then move the new system ﬁle

into place.

mv /stand/system /stand/system.prev

mv /stand/build/system /stand/system

e. Prepare for rebooting by invoking the kmupdate command. This sets a

ﬂag that tells the system to use the new kernel when it restarts.

/usr/sbin/kmupdate

Step 3. Notify users that the system will be shut down to conﬁgure the tape

drive. You can use the wall command and/or the interactive capabilities

of the shutdown command to broadcast a message to users before the

system goes down. See wall (1M) or shutdown (1M) in the HP-UX

Reference.

Step 4. Bring the system to a halt, using the shutdown command.

Step 5. Turn off the power to all peripheral devices and then to the SPU.

Step 6. Install the hardware, following instructions shown in the hardware

documentation. When attaching the tape drive, set the switches on the

tape drive to an unused address, which you will have determined from

ioscan output. Use the cabling recommended in the hardware

documentation. If installing a SCSI device, make sure the last device in

the SCSI chain is terminated.

Step 7. Turn on the power to all peripheral devices. Wait for them to become

"ready", then turn on power to the SPU.

On booting up, HP-UX detects the new tape drive and associates it with

its device driver. insf creates the character device special ﬁles required

to communicate with the tape drive.

Step 8. Verify the conﬁguration by invoking the ioscan command to conﬁrm

that the tape device is present and device special ﬁles have been created

for it.

In the sample output shown, the tape driver at hardware path

2/0/1.3.0 can be accessed by one of eight device ﬁles.
