현재 카드는 정상적으로 fumsutil에 online상태입니다.



어떤 현상으로 나타났는지. 경험하신 분 답변부탁드립니다. 그럼.

dmesg에 나타난 내용분석

경험은 해 보지 못했지만.. 위 에러로그로 ITRC를 찾아 본 결과

현재 카드에 fc cable로 연결된 디바이스가 있다면 아래 내용처럼 잘 못된 설정으로 생긴 문제라고 합니다...

패치나 소프트웨어가 정상적으로 설치되었는지 아래 내용을 참고하셔서 체크해 보시기 바랍니다..^^

그리고 만약 FC카드에 어떤 디바이스도 연결되어 있지 않다면

/var/stm/config/sys/diaglogd.cfg 파일에 아래내용을 수정하여서

dialogd데몬을 Restart하면 됩니다.

그러면 에러메세지를 더 이상 뿌리지 않습니다..

#/var/stm/config/sys/diaglogd.cfg 파일에 아래 내용 수정.

Good day^^

PROBLEM

A system is getting the following errors in dmesg and syslog. He gets

the errors when he runs ioscan -fn and when system boots all devices

are available.



Jan 16 15:37:12 reaper vmunix: ct_query failed. hw_path = 0/0/8/0/0

Jan 16 15:37:14 reaper vmunix: ct_query failed. hw_path = 1/0/8/0/0



What does this mean?











RESOLUTION



The system has the following driver installed:



FibrChanl-00 B.11.11.09

PCI/HSC FibreChannel;Supptd HW=A6 684A,A6685A,A5158A,A6795A



Also has the following patches:



PHKL_27579 SCSI IO Cumulative Patch

PHKL_27751 Fibre Channel Mass Storage Patch

PHSS_26799 Tachyon TL Fibre Channel Driver Patch



The fcmsutil output on the td3 card is:



Vendor ID is = 0x00103c

Device ID is = 0x001029

XL2 Chip Revision No is = 2.3

PCI Sub-system Vendor ID is = 0x00103c

PCI Sub-system ID is = 0x00128c

Topology = PTTOPT_FABRIC

Link Speed = 2Gb

Local N_Port_id is = 0x610813

N_Port Node World Wide Name = 0x50060b000011c6bb

N_Port Port World Wide Name = 0x50060b000011c6ba

Driver state = ONLINE

Hardware Path is = 0/0/8/0/0

Number of Assisted IOs = 0

Number of Active Login Sessions = 0

Dino Present on Card = NO

Maximum Frame Size = 960

Driver Version = @(#) PATCH_11.11: libtd.a : Jun 28

2002, 11:08:35, PHSS_26799







A review of the ioscan output shows no devices configured at td1 path

and td3:



fc 3 1/0/8/0/0 td CLAIMED INTERFACE HP Tachyon

XL2 Fibre Channel Mass Storage Adapter

/dev/td3

ba 16 1/0/10 lba CLAIMED BUS_NEXUS Local PCI Bus

Adapter (782)





The fibre channel cards are connected to the switch but no devices were

configured. The system admin did not zone any devices to be seen by this

card.



To summarize, here is a short definition of what ct_query is doing:



CT stands for Common Transport. FC-CT protocol is the protocol used to

communicate with services on the switch/fabric. These services are referenced

through well-known N_Port IDs. An example of such a service is the Name Server

which resides at N_Port ID 0xFFFFFC. We can think of CT Server as a superset of

Name Server.



#ITRC문서 2

ct_query is Common Transport protocol which is used with Fibre Channel.



For new installs, it indicates something wrong with the configuration,maybe a card not completely installed, etc.



You need to verify that you have the right software/patches installed http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl? productNumber=A5158A&oper=install

(this link is for the A5158A product)



If you have Diagnostics installed you may also see errors there as well that state:

Possible Causes/Recommended Action:

The device has been misconfigured or is in an error state. More information may be available via the "ioscan" command.
