can't access tape array

[Alexander Schnapper]

Hello,

i have got a rx7620 itanium2-server which has a scsi-connection to a tape array and to a disk system. The connection to the disk system is ok, but i can't access the tape array. The tape array has al its terminators and is configured properly.

I am trying to access the tape array through console and with hp-ux 11i (Foundation OE).

I have tried all possible commands of "ioscan", but i still can't see and access the tape array. (StorageWorks Tape Array 5300).

Can someone help? Thanks a lot,
Greetings from germany,

hi,

are the correct drivers enabled in the kernel?

regards,
Thierry.

Check your tape driver.
# kcmodule | grpe stape

output will be
stape Y -

If output is not correct you must install driver.

To install tape driver
# sam
Kernel Configuration => Driver => select stpae => Action => Add driver to Kernel

And then Reboot your system.

This happens if you install the OS when tape is not connected. As suggested check the drivers presence in the kernel. lsdev for list. Open sam and go to tape drives and select diagnose missing device. It will automatically add most tape drivers to kernel.

TT is correct. If you do not have a tape drive of any type attached when the system is built nonoe of these drivers will be installed. The drivers your after are:
sctl
schgr
stape

Hi Alexander,

tape array 5300 in itself is not a device. There are pluggable modules onto the array. You can plug DVD modules or tape modules onto it. What have you connected?

Check the SCSI cable is connected to the same half as of the device plugged in and that bus should be terminated or daisy chained to the other half.

If you have got the tape module, then follow TT's suggestion.

Cheers,
Mohan.

Hi and thanks for your responses,

i installed the machine without the tape array. That could have been the problem. At the moment i am reinstalling it. Takes another 20 mins and then i'll report what happend if i use the tipps from TT.

Until later,
Alexander

Back again ...

Ok, i installed HP-UX 11i Foundation again and tried the command:

kcmodule | grep stape

but it didn't work. The only output which i received was:

WARNING: The directory /usr/conf/lib contains a file '/usr/conf/lib/ots_q4.o' which is not a kernel code library. This file will not be used.
stape static best


And i somehow can't access the Kernel Configuration - SAM only gives me a Kernel Config (web)... And through console it seems, that it doesn't work...


Any idea?
Thanks,
Alex :-)

Alex,

With HP-UX 11i version 2 for Itanium servers, you are only provided with kcweb to access the kernel configuration and this has to be ran from some form of X-windows or from a web browser to https://"server IP"/kcweb. This is now the only method of configuring the server that I know of.

Sorry the web address is incorrect it should be.

https://SERVER IP:1188/casey/login.cgi

This will take you to the login screen. Once logged in, will give the kernel parameters.
