ESX 4.0 hosts causing SCSI Hung Commands on Adapter

I have two new ESX 4.0u1 hosts that I am storage migrating VMs from an old HP EVA world to the new NetApp world (3170s running 7.3.2). During migration to the new NetApp Datastores and migration to the new hosts (thus transferring i/o from the 3.5 world to the 4.0 world ) we will get a Hung Command on one of the Target Adapters that requires a config down and then a config up to clear. This Hung Command prevents all i/o to that target and makes on of the paths dead on both ESX 4.0 hosts. Other hosts that are accessing that path also lose connectivity to their LUNs via that adapter port. What I am trying to figure out is why is this happening, and why are no ASUPs being generated or why is there no way to clear the hung command, other than to do an adapter reset?

I have ALUA enabled on the igroup and am using the VMW_RR_PSP.

I am zoned from my hosts to all front end ports on the NetApp, two fabrics. So I have 8 paths to the disk (4 Active I/O and 4 Active).

I have a ticket open with NetApp but am wondering if this is really an ESX issue.

errors from esx logs:

I am seeing this with my Emulex HBAs too, in fact it seems to cause my entire ESX environment to die while it is timing out...

Try using VMW_PSP_MRU for path selection.

Because in ESX4.x if you list the satp rules. It says

Name                                  Vendor   Model                               Driver  Transport  Options  Claim Options    Description

VMW_SATP_ALUA    NETAPP                               tpgs_on                                                 NetApp with ALUA

And then if you check the default psp for VMW_SATP_ALUA  satp it is.


Name                             Default PSP            Description

VMW_SATP_ALUA        VMW_PSP_MRU    Supports non-specific arrays that use the ALUA protocol

Thanks,

-A William

We encounter the same problems in our environment.

Two FAS3040 active/active and out ESX Hosts show theses messages throughout the day. Despite you we use QLOGIC HBA.

Are those messages critical, or can we ignore these?

Whether we use VMW_PSP_MRU or VMW_PSP_RR does not make any difference. Should we open a ticket for this at VMware or is this still a NetApp Problem ?

James,

Did you ever get a fix for this issue, we are doing almost the same migration process from HP EVA to V-Series3240's but our ONTAP version is 8.0.1P3

At the moment write I/O to the NetApp doesn't happen and we are seeing the same sense code messages" failed H:0x2 D:0x0 P:0x0 Possible sense data&colon; 0x0 0x0 0x0"

Many thanks

There's a good chance you'll want to update to 7.3.2P6....especially if what you're running into is related to this bug.

I don't see how the fix applies.  Seems specific to a 31xx and I have a similar issue with 6040.

Hey All,

I'm not sure I can "fix" all of these issues through the support forums, but I'll provide what info I can to help, and feel free to direct message me with your NetApp case numbers and we can go through the host and controller data to find the "real" RCA for all of this.

From your messages (vmkernel) logs in the first part of the post, you're receiving the following errors: failed on physical path "vmhba2:C0:T3:L11" H:0x7 D:0x0 P:0x0 Possible sense data&colon; 0x0 0x0 0x0.

Using the VMware NMP host side debug (because the error is on H: - host, not 😧 - device): http://kb.vmware.com/kb/1029039 we can decode this to mean:

This status is returned when a device has been reset due to a Storage Initiator Error. This typically occurs due to an outdated Emulex HBA firmware or possibly (though rarely) as the result of a bad HBA. 

For more information on the bad HBA scenario, see One host shows a Storage Initiator Error while all other hosts show SCSI Reservation Conflicts (1021187).

In addition to a bad HBA possibility, when this is occurring on all paths on all hosts, I'd recommend verifying the firmware on the interconnects and switches connecting the hosts or blades to the fabric.  We have also seen this when there is a high fan in ratio from the blades through the interconnect (creating severe congestion in the interconnect), and when there is a bad connection or faulty SFP within the fabric or on an ISL.

From the second chunk of vmkernel logs, you're receiving: failed on physical path "vmhba2:C0:T2:L6" H:0x1 D:0x0 P:0x0 Possible sense data&colon; 0x0 0x0 0x0.

You can use the same VMware KB above to diagnose this, and find it is pointing to "No Connect", which we typically see in the event that you still have a phyiscal connection to the fabric, but the controller isn't visible to the host because of dropped frames or congestion issues.  If this is happening on more than one host, it is likely there is a fabric communication problem (likely due to a firmware compatibility issue).
