powerpath 4.5.0 hpux write error

[Gerrit_1]

Hi,

At the moment we're upgraden our naviagent and
powerpath-software on HPUX 11.0

Naviagent from 6.7.0.4.7 to 6.19.1.3.0
Powerpath from 4.1.0 to 4.5.0

I've a host with 2 fibre-cards and 2 zonings :
HBA0 --> SPA CX600
HBA1 --> SPB CX600

All the luns have default : SPB
When I remove this zoning, everything looks ok
but I see 'strange' loggings, any idea ?

Shalom tx,

Check the world wide name (WWN) on the zoning configuration.

The zonings are ok.
The luns are visisble through 2 paths.

I'm just testing that the powerpath-soft is
working ok.
I'm worried about the read/write errors.

Hi Gerrit,

If luns are tresspassing continously from SPA to SPB you should stop this happening. check for the basic setting like "Failover mode", "array comm path" and most important "Initiator type".
