4. From the right-hand panel on the HP-UX Peripheral Device Tool page, click on Reinstall Device

Files. At the next page, click the Reinstall button. When the browser returns to the HP-UX

Configuring an autoloader

1. Reboot the system with the autoloader attached.

2. Run

ioscan -funC autoch to find the device files for the autoloader.

If there are no device files listed, proceed as follows:

3. Create

/dev/rac if it does not exist.

4. Run

ioscan -funC tape to find the tape device file.

5. Execute:

ls -al /dev/rmt/<device_file>

This will return an output similar to:

2 bin bin 205 0x0450c0

This example tells you that the card number is 4 and the target number 5.

6. Run

mknod to create the device files:

mknod /dev/rac/c<X>t<Y>d<Z> c 203 0x0<X><Y><Z>00

where:

<X> is the card number

<Y> is the target number

<Z> is the LUN

1. Depending on how SMH was last used the HP-UX Peripheral Device Tool page will display either the Agile View or the

Legacy View as referenced in the Introduction to this chapter (page 9). To switch between these views use the Toggle

Global Device View link on the right hand side of the HP-UX Peripheral Device Tool page. In this chapter, the Agile View

is assumed. The process is similar for the Legacy View.
