Storage = Netapp 3140

Thanks

How is the NETAPP connected? FC or iSCSI?

Note that LVOL on iSCSI is not supported for backing store. See HPVM documentation.

Hi,is connected by FC.

When install guest using local lv (Disk internal), the installation finish OK.

Thanks

[Stan_M]

You may want to speak to netapp in that case.

[Swift16v]

I suspect it's a problem of HPVM by:

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=4146186&prodTypeId=18964&objectID=c03436478

I have others HP-UX 11.31 connected to Netapp3140 without problem.

[Stan_M]

That article only generally points to performance hints and doesn't provide root cause.

You already are using AVIO.

I'd really speak to Netapp...

[Swift16v · Accepted solution]

Hi,
I solved the issue changing the following

1. Change the policy to cell locality based round robin as follows:

scsimgr set_attr -D /dev/rdisk/disk8 -a load_bal_policy=cl_round_robin;

2. And set preferred path:

scsimgr save_attr -D /dev/rdisk/disk8 -a load_bal_policy=preferred_path -a preferred_path=0/0/0/5/0/0/0.0x500a0983893b4a6b.0x4000000000000000;

This suggests that the array's FW did not properly supply ALUA information
