EVA disk not visible to K570 with A6685A

[Simon Galton]

We're having some trouble getting a K570 with an A6685A FC card to see disk from an EVA5000 (HSV110). The server is running 11iv1.

It _can_ see the disk from our two va7410s on the same fabric, but the EVA disk does not appear in an ioscan report. Our zoning permits these devices to see one another. The EVA has been instructed to present the vdisk to this host, I have double-checked the WWN.

I have installed the latest HWEnable11i and the GoldBase11i patch bundles.

Any advice?

Can you attach the output of ioscan -fn and
fcmsutil /dev/td0 get remote all

Use /dev/td0 or /dev/td1 or whatever your HBA is.

Any you are sure you set the OS to HPUX on the eva - host configuration and you are presenting the LUN to the port WWN of the HBA

[Simon Galton]

I've attached the requtested outputs.

The EVA is okay -- all the other UX nodes can see their LUNs. I've also checked the WWN again and can confirm that it's presenting the vdisk to the correct port WWN of the K570's HBA.

make sure you didnt accidentally grab the wrong wwn by confusing nport node and nport port the two numbers are very close, and the 0x, it denotes hex doesnt go in the EVA config.
make sure zoned right
make sure you saved the zone config
make sure you Enabled the zone config
#very important. Also sometimes the fabric is too busy so these will fail so be sure and pay attention to the output. They do not autoretry.

double check the wwn in your hostgroup in the eva
do an ioscan on hp machine
then do an insf -e
then do ioscan -fnC disk
check dmesg
and /var/adm/syslog/syslog.log for any suspicious messages

If you have a very large san environemnt you could have run out of chanel numbers.

When it is working.
Dont present huge single disk to create a volume group. Carve smaller like sized disks to create a volume group, then do a lvcreate -L size -i -I
the two Is are for stripe size and the number of disks in the volumegroup/stripe

Your performance will be better.
*Note you should use Securepath for this type of san even though pvlinks will most likely do the job.

You aren't even seeing the eva at the HBA level. Only 2 ports are showing up, those attached switch ports 3 and 4 (the va)

Are you sure you enabled the zones after adding the the wwns to the ports.
[It's easy to save but not enable the zone, or create a zone and forget to add it to the zone set.]

If the switch is a brocade, you can telnet to it and do a:

zoneshow:

The last part will show the actual zoning that is in effect.

Aha! Your comment:

"Are you sure you enabled the zones after adding the the wwns to the ports.
[It's easy to save but not enable the zone, or create a zone and forget to add it to the zone set.]"

made me double check our zone settings and you're right -- the new config was saved but not enabled!

While I'm embarassed, I'm also glad it was so straight-forward to resolve.

Thanks for your help, folks.
