HP StorageWorks Autoloader 1/8 Ultrium 460: Installation problems

[Yogeeraj_1]

Dear experts!

We are currently in the process of configuring an HP autoloader on our RP5400 (L1000).

Using the information in the whitepaper: How to configure a tape library in HP-UX, we have gone through most of the steps rather successfully! However, when using the mc command to check the configuration, we are getting the following error message:
# mc -p /dev/picker -q
ERROR: 0x5 Illegal Request : 0x2400 Invalid field in command descriptor block #

Below, details about how the Autoloader identified itself tou our system upon first connection to the SCSI port:
=============================================

The thing claims to be: HP Ultrium 2-SCSI F7BP
# mc -p /dev/picker -q

Did we miss something?

thank you in advance for your replies.

Hi


See if the permissions on the /dev/picker are limited

May be thinking it is busy

Set them on full for everybody

Try again

hi steeve steel,

thank you for the reply.
the permissions are ok!

# cd /dev/
# ll picker
crw-rw-rw- 1 root sys 203 0x005000 Mar 11 11:32 picker
# mc -p /dev/picker -q
ERROR: 0x5 Illegal Request : 0x2400 Invalid field in command descriptor block
#
