Cannot connect to Tape drives

[P. Prinsloo]

I have a N4000 with 6 A5158A fiber cards installed. Two of these cards are connected to EMC disks, there is no problem here. Two of the other cards are connected to a StorageTek Robot via fibre cable. When I do a ioscan on the hardware path I get the following :Class I H/W

The tape is unclaimed, I cannot connect to it.

I have checked the driver I have installed for it and when I do swlist this is what I get.
A5158A
B.11.00.05 HP PCI Tachyon TL Fibre
Channel.

Additionally the Fibre Channel Mass Storage Driver patch PHKL_23939 is installed on this machine.

Can anyone help me to see the tape drives ( according to StorageTek the drive are on abitrated loop)

Hi,

You need to set up a robotic arm device
and add the appropriate kernel driver.

The attached document will tell you how.

I dont think you have the correct driver loaded for the tape library, thats all. Its either tape2 or spt. It should be added to the /stand/system file and look like this;

driver 1/10/0/0.8.0.255.0.1.0 spt
or
driver 1/10/0/0.8.0.255.0.1.0 tape2

Try spt first, rebuild then kernel and reboot and see if you can see it CLAIMED now.

If your using OmniBack, bear these items in mind.

Turn off EMS monitoring to your tape drives. Make sure that you have the latest SCSI patches loaded for your OS level. Have the 'st_ats_enabled' parameter set to '0'. Have your library in Omniback set to eject tapes instead of aborting, this will return tapes to slots instead of leaving them stuck
in drives.

Hi it's been a long time since i set a library up & I could be wrong but I seem to remember for our K servers the sctl driver was needed. We then had to manually bind the driver to the device. Could be totally wrong as that was 3.1 on hpux 10.20.
