what is lpfc_do_dpc_0?

[Tolga Evren]

Hi,

Thanks for your responses. Yes my system is connected to the emc storage
. I use emulex HBA . I have checked the messages file , there exists
following messages:

Nov 13 20:39:47 tanidw1 kernel: !lpfc0:0410:INe:Cannot find virtual addr
for mapped buf on ring 0 Data x411ACC00 x x
Nov 13 20:48:19 tanidw1 kernel: !lpfc0:0410:INe:Cannot find virtual addr
for mapped buf on ring 0 Data x411AC800 x x
Nov 13 20:57:11 tanidw1 kernel: !lpfc0:0410:INe:Cannot find virtual addr

Nov 13 21:04:54 tanidw1 kernel: !lpfc0:0410:INe:Cannot find virtual addr
for mapped buf on ring 0 Data x411AC000 x x


Do these messages indicate a problem?

Kind Regards,
Tolga Evren

lpfc might be related to an Emulex LP fibre adapter.  Are you SAN
connected?  RHEL 2.1 is fairly old but you might see if your fibre
drivers and firmware are current.  Also, check for any lpfc-related
events in /var/log/messages
