Cann't present luns to hp-ux v11.31

[Alexander Ketshvili]

Hi gurus
I have a question about how to present a storage EVA 4000 lun to the hp-ux v 11.31.

I pluged in a HBA, configure san switch, and now i can see the following

# fcmsutil /dev/fcd0

Vendor ID is = 0x1077
Device ID is = 0x2432
PCI Sub-system Vendor ID is = 0x103C
PCI Sub-system ID is = 0x1705
PCI Mode = PCI Express x4
ISP Code version = 4.4.4
ISP Chip version = 2
Topology = PTTOPT_FABRIC
Link Speed = 4Gb
Local N_Port_id is = 0x680a00
Previous N_Port_id is = None
N_Port Node World Wide Name = 0x5001438000c0b219
N_Port Port World Wide Name = 0x5001438000c0b218
Switch Port World Wide Name = 0x2008000dec471f00
Switch Node World Wide Name = 0x2001000dec471f01
N_Port Symbolic Port Name = hpux2_fcd0
N_Port Symbolic Node Name = hpux2_HP-UX_B.11.31
Driver state = ONLINE
Hardware Path is = 0/3/0/0/0/0
Maximum Frame Size = 2048
Driver-Firmware Dump Available = NO
Driver-Firmware Dump Timestamp = N/A
Driver Version = @(#) fcd B.11.31.0903 Dec 14 2008

there is the following output for the ioscan

ioscan -funC disk
Class I H/W Path Driver S/W State H/W Type Description
==================================================================
disk 0 0/2/1/0.0.0.0.0 sdisk CLAIMED DEVICE HP IR Volume
/dev/dsk/c0t0d0 /dev/dsk/c0t0d0s2 /dev/rdsk/c0t0d0 /dev/rdsk/c0t0d0s2
/dev/dsk/c0t0d0s1 /dev/dsk/c0t0d0s3 /dev/rdsk/c0t0d0s1 /dev/rdsk/c0t0d0s3

The lun is created corretly on EVA and is presented. I was able to present this lun to the hp-ux B.11.23 May be there is a driver problem or other suggestions?

Shalom,

Your fcmsutil output shows a perfectly good connection.

The fiber switch is fully visible.

So long as you are not using Oracle RAC try:

insf -e -C disk

That should detect properly presented LUNS.

Did you try just a

ioscan
then
ioscan -Cdisk
ioscan -fnCdisk
?

Is this the same system that was the 11.23 system and you upgraded it
or
a new system?

ooops
I meant
ioscan
insf -Cdisk
ioscan -fnCdisk
.

Gives the details of your presentation of the LUN to this host,
such as
LUN #
WWNs assigned to the host entry in EVA
.

Are you using power path? if the following commands don't present the disk, then you either have a problem with zoning/masking or your FA settings needs to be configured for 11.31

ioscan
ioscan -d sdisk
powermt config
powermt save
powermt display
ioscan -m dsf

Powerpath?
This would not make sense ...
Check again if the vdisk is presented in hpux mode

[Norman_21]

I'm not suggesting that power path is the issue. In fact, you don't need power path with the luns in 11.31 unless it's a company policy. However, we had to set an additional flag for the luns in 11.31 at the FA port level. We have EMC storage though.

>I'm not suggesting that power path is the issue

I've never used Powerpath.
I wouldn't expect it prevent the legacy devices from showing up in ioscan -- but I'm just guessing.

For me, there are too many unanswered questions about the origins of this box and its relation to the "11.23" box, the HBAs, the EVA host definition, etc.

I would like to know exactly what the presentation looks like on the EVA.

If the WWN
0x5001438000c0b218
is showing up in the EVA,
then it can't be a zoning issue.

If he has
correctly added this port
to the correct host entry
& presented the LUN to the correct host
well then ...

ioscan should see it
.
