qla2xxx [0000:xx:00.x]-801c:4: Abort command issued nexus=x:x:x -- 0 2002

Hi,

Here is our environements information:

 

Server: HPE DL580 G9

HBA: SN1000Q

OS: Oracle Linux 6.8

SAN Switch: Brocade 6520

SFP: 16 Gb/s

 

There is no hardware fault but we are facing with:

 

qla2xxx [0000:xx:00.x]-801c:4: Abort command issued nexus=x:x:x --  0 2002

 

It will happen on one of HBA ports randomly and then Oracle DB will be crashed.

We have upgraded Fabric OS to latest version but nothing changed. HBA has been replaced with another one but no luck.

OS configurations have been changed, HBA speed has been changed and many other things but still no luck.

 

Can anyone help me to resolve this issue?

I don't have any experince with Oracle Linux, but from you description the issue sound like a malconfigured Multipath.

 

the issue is not related to Switch or FOS code.

I also know nothing of Oracle Linux.

 

That typed: https://support.hpe.com/hpsc/doc/public/display?docId=mmr_kc-0123922

 

Also, on the switches connected, login as admin and run the following:

 

sfphow -all | grep -e Port -e Power

Re: qla2xxx [0000:xx:00.x]-801c:4: Abort command issued nexus=x:x:x -- 0 2002

َActually, I did many changes on multipath such as changing Path Checker, increasng dev_loss_tmo and others.

Also I changed whole multipath configuration according to EMC Connectivity Guide but issue was presists.

Is there any specific configurations when target and initiator has different speed?

Our VNX using 8 Gb/s ports but servers have 16 Gb/s HBA.

@Davoud Teimouri

 

just a quick comment, in the future when you open a thread post all info about you environments, it make a lot of sense and makes things easier.....

 

VNX required on switch side that Fillword is set to Mode 3, which in your case does not matter, because fillword cannot be lomg set on Gen5 platforms, but in some circumstance other settings are required and mandatory.

 

try follow:

 

-set the switch port as fixed 8G instead AN ( portcfgpersistendisable / portcfgpersistentenable )

-force the HBA at 8G

-disable QoS on those port's, both Target and Initiator

Thanks for your response.

Should I run this on initiator ports? "set the switch port as fixed 8G instead AN ( portcfgpersistendisable / portcfgpersistentenable ) "

Also about HBA speed, should be configured via HBA BIOS?

Hi,

 

did you check the entire path to the storage including possible ISLs for e.g. physical layer issues. And have you checked with the storage vendor on their view of the issue?
