HP-UX11.11 and DP6.0


I have a HP StorageWorks EML E-Series connected to the SAN, DP6.0 running on a windows Server 2003 cell manager and a mixture of servers, windows, linux and hp-ux.

My Problem: All systems with the execption of HP-UX 11.11 can see, erad and write to the 8 drives on the library.

HP-UX 11.11 CANNOT see the drives from DP6.0
IOSCAN shows tape devices CLAIMED, see evbra -dev results attached are two documents devbra debug and ioscan/devbra output in zipped file.

Kernel drivers esctl, sctl and schgr are loaded.

Now idea wht devbra see /dev/spt and not /dev/rmt for tape devices.

TIA
David

Hi,
We don't see the output.
The EML is connected using fibre? You will perhaps need the FCD driver or the FCP driver.
Hope it helps

Re: HP-UX11.11 and DP6.0

What's exactly the message you have on DP?

In fact I don't understand hpux 11.11 cannot see the drives "from" dp6.0 and ioscan shows them CLAIMED on hpux.

Some suggestions.
Do you patche with the core and the media agent the hpux 11.11?
When you do a ioscan -fnk do you have something UNKNOW?
Do you have err/messages on syslog.log or in EMS?
Do you patch the stape, scsi etc?

Re: HP-UX11.11 and DP6.0

Trying to look at the devbra debug, but ITRC is not retrieving the zip file right now. The problem should be clear in the debug, once I can open it.

Thanks,
Scott

Answers to above questions:
Smatador: 1) No device found (DP message when config drive)
2) Cannot see drives from DP6.0 on HP-UX 11.11 systems, 11.23 & 11.31 no problem
3) yes - from ux11 installation server
4) no -unknown none
5)no -err messages
6) latest patches on system

Scott: When running devbra -dev I get the following output
cptux02/>/opt/omni/lbin/devbra -dev
/dev/spt/c3t2d0: Unsupported special file type!
/dev/spt/c50t0d0: Unsupported special file type!

Now check the results when I move /dev/spt out of the way,

Even though I cannot 'see' the drive from DP, I can configure it manually and use it.

Problem: /dev/spt gets created again and I loose the drives.

spt driver not loaded into kernel so why does /dev/spt get recreated?

Re: HP-UX11.11 and DP6.0

Hi
Do you disable this driver on the kernel?
I don't have now a hpux to test, but normally SAM ---> Kernel Configuration ---> Drivers ---> set spt to Out or remove and reboot.
Check also the /stand/system.
Hope it helps

Re: HP-UX11.11 and DP6.0

Smatador:

The driver is OUT of the kernel.

Have removed /dev/spt and rebooted system and /dev/spt is re-created. WHY?????? 😞

Re: HP-UX11.11 and DP6.0

Do you check /stand/system
Manually (not using SAM) delete the spt driver from the /stand/system file and generate a new kernel (mk_kernel), reboot.
Hope it helps

Re: HP-UX11.11 and DP6.0

You don't need the spt driver, do not bother with that.

I need the debvbra debug file. Maybe retry attaching that. The previous zip file still refuses to open.

You say this is 11.11 but refer to esctl. That's an 11.31 thing. So I'm a little confused.

Thanks,
Scott

Re: HP-UX11.11 and DP6.0

Hi Scott,

I have attached the devbra debug logfile.

Was told by hpsupport to load the esctl driver.

Understand that I dont need spt driver, but why does spt devices files get built again after I remove them?

Thanks
David

Re: HP-UX11.11 and DP6.0

Well, the only clear cut failure in the debug is the errno 17 on the mknod command. Net result is the devices are not added to the file to query later to see what devices to inquire and configure. So nothing gets seen.

Delete everything in /dev/spt (I'm assuming you do not intentionally have any /dev/spt device files) and then retry the devbra. errno 17 is file already exists.

The files are sctl device files, not spt device files, as noted by the 203 major number. Maybe there are files already there with an incorrect major number so we're not overwritting them with sctl majors?

No idea why they had you add esctl, nor what that's suppose to accomplish.

Thanks,
Scott

Re: HP-UX11.11 and DP6.0

Thanks Scott,

That's the same thing I noticed in the debug log, But see my 4th reply above. I have tried removing /dev/spt, then YES I can run devbra abd see the devices but these cursed spt device files keep getting created and messing things up 😞 This is happening on all my 11.11 systems.
