hpux seing the lun with eva5000

I'm new to the hpux os. I'm trying to see the lun I created for the box. I type in ioscan and I don't see the lun. Do I need secure path?
Any help would be appreciated.

Re: hpux seing the lun with eva5000

Hi Dave

After lun creation you have to install special file as per following:

#insf -e

Thereafter ioscan will show device files related to created lun

Re: hpux seing the lun with eva5000

In order to see the EVA5000 you do not need secure path.
You can connect it single path.
See this for information ftp://ftp.compaq.com/pub/products/storageworks/whitepapers/5982-1850EN.pdf

If you connect an HP-UX server such that it can see more than one port of the EVA you will need secure path to deal with the different presentations of the same LUN over the two controllers!

But anyway you should see it.
You need to present the LUN to the server.
For step by step instruction see the HP-UX EVA guide here:

http://h200001.www2.hp.com/bc/docs/support/SupportManual/c00308509/c00308509.pdf

Re: hpux seing the lun with eva5000

Hi Dave,

here are the steps:

Install all patches (QP, HWE & Secure Path patches)

You have an EVA5000 then you need secure Path 3.0F (in the moment)

After installing SP you can do an ioscan and go on with an insf -e

For Connecting an EVA3k or 5k you need Secure Path (and important: Install patches - list in release nodes), for the 4k 6k or 8k you can use pvlinks...

Re: hpux seing the lun with eva5000

You don't need to have SP. You can see the LUNs presented through the host.
After presentation you need to run
# insf -e -v -C disk
# ioscan -fnC disk

You should the devies files there and the device status as CLAIMED.

Then you can go ahead the configure the LUN in LVM as per your need.

Re: hpux seing the lun with eva5000

still didn't work. I went into command view and everything looks good there.

Re: hpux seing the lun with eva5000

Hi Dave,

there are a lot of "NO_HW" entries in your ioscan. Please check your syslog file for entries.

Hope this helps!

Re: hpux seing the lun with eva5000

syslog in the host? What am I looking for?

Re: hpux seing the lun with eva5000

Those devices should not be in No_HW state. Moreover there should be one more entry for
hsx if you get EVA LUN presented to the host successfully. Eithere is a connection problem or FC driver issue.
The entry for ext_bus with fcparray is missing!!! I bet it is driver issue.

There should be two product installed and shown in swlist -l product
FC-TACHYON-TL and FCMassStorage

Can you put following here
# swlist -l product
# fcmsutil /dev/td0
# fsmsutil /dev/td1

How the EVA is connected physically to the host. Pls provide more details to assist you

Re: hpux seing the lun with eva5000

I'm attached to a switch attached to the eva. Nothing funky. Thanks

Re: hpux seing the lun with eva5000

Hi,
Is the HBA visible from the EVA ?
Have you created a host in the EVA and assigned the HBA to the host ?
Is the LUN presented to the host ?

Is the HBA visible from the switch (I belive you have some tool to monitor the switch) ?

Switch zoning OK ?

Is link up (LED on both switch port and HBA) ?

Dave,

Are the correct drivers in the kernel? If not you may have to add them and reboot the system.

Re: hpux seing the lun with eva5000

Hi everyone thanks for helping. I realize I have a bigger problem. We aren't seeing windows hosts either. I'm going to try and figure it out today. I will let you know.

Thanks again.

Re: hpux seing the lun with eva5000

I'm ending this post. I tried with a brocade switch and it worked. I originally had a mcdata. I tried with a diffent box running command view and it worked with both switches. Anyway thanks everyone.
