소개

서버에 상주하는 Cisco iSCSI 드라이버는 iSCSI 솔루션의 핵심 구성 요소입니다. 이러한 iSCSI 드라이버는 SCSI(Small Computer System Interface) 명령을 가로채고 IP 패킷으로 캡슐화한 다음 Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2 또는 Cisco MDS/IPS-8.This으로 리디렉션하여 HP-UX iSCSI 호스트를 SN 5428로 구성하는 샘플 구성을 제공합니다.

사전 요구 사항

요구 사항

이 구성을 시도하기 전에 다음 요구 사항을 충족해야 합니다.

HP-UX 버전과 호환되는 iSCSI 드라이버를 설치합니다.최신 버전의 드라이버는 Cisco.com의 Cisco iSCSI 드라이버(등록된 고객만 해당) 다운로드 페이지에서 찾을 수 있습니다. README.txt 파일은 드라이버 zip(tar) 파일에 포함되어 있습니다. README에는 라이센스 계약서, 드라이버 설치 및 구성 지침, 드라이버 아키텍처의 기술 개요에 대한 정보가 포함되어 있습니다.
운영 체제 요구 사항 및 패치 요구 사항은 HP-UX 릴리즈 노트의 Cisco iSCSI Driver의 시스템 요구 사항 섹션에 설명되어 있습니다.

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.

표기 규칙

이 문서에서 사용되는 Cisco MDS 9000은 MDS 9000 제품군(MDS 9506, MDS 9509, MDS 9216)의 모든 FC(Fibre Channel) 스위치 제품을 나타냅니다. Cisco IPS(Intrusion Prevention System) 블레이드는 IP Storage Services Module을 가리킵니다. 문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 표기 규칙을 참조하십시오.

배경 정보

Cisco IPS(Intrusion Prevention System) 모듈은 FC(Fibre Channel) 스토리지 디바이스에 대한 IP 호스트 액세스를 제공합니다. IPS 모듈은 DS-X9308-SMIP입니다. 투명한 SCSI 라우팅을 제공합니다. iSCSI 프로토콜을 사용하는 IP 호스트는 FC 네트워크의 iSCSI 대상에 투명하게 액세스할 수 있습니다. IP 호스트는 TCP/IP 연결을 통해 iSCSI PDU(Protocol Data Units)에 캡슐화된 SCSI 명령을 MDS 900 IPS 포트로 전송합니다. IPS 모듈에서 연결은 적절하게 구성된 GE 인터페이스 형식으로 제공됩니다. IPS 모듈을 사용하면 가상 iSCSI 대상을 생성하여 FC SAN에서 사용 가능한 물리적 FC 대상에 매핑할 수 있습니다. 물리적 대상이 IP 네트워크에 연결된 것처럼 IP 호스트에 FC 대상을 표시합니다.

IPS 모듈을 통해 스토리지에 액세스해야 하는 각 iSCSI 호스트에는 호환되는 iSCSI 드라이버가 설치되어 있어야 합니다. iSCSI 프로토콜의 도움을 받아 iSCSI 드라이버를 사용하면 iSCSI 호스트가 IP 네트워크를 통해 SCSI 요청 및 응답을 전송할 수 있습니다. 호스트 운영 체제의 관점에서 iSCSI 드라이버는 호스트의 주변 장치 채널에 대한 FC 드라이버와 유사한 SCSI 전송 드라이버로 나타납니다. 스토리지 디바이스의 관점에서 각 IP 호스트는 FC 호스트로 표시됩니다. IP 호스트에서 FC 스토리지 디바이스로 SCSI를 라우팅하는 작업은 다음과 같은 주요 작업으로 구성됩니다.

호스트와 IPS 모듈 간에 IP 네트워크를 통해 iSCSI 요청 및 응답 전송
IP 네트워크의 호스트와 FC 스토리지 디바이스 간의 SCSI 요청 및 응답 라우팅(iSCSI를 FCP로, FCP를 iSCSI로 변환). 이 라우팅은 IPS 모듈에서 수행됩니다.
IPS 모듈과 FC 스토리지 디바이스 간에 FCP 요청 또는 응답 전송

IPS 모듈은 기본적으로 FC 대상을 iSCSI로 가져오지 않습니다. IPS 모듈이 FC 대상을 iSCSI 이니시에이터에서 사용할 수 있게 하려면 동적 또는 정적 매핑을 구성해야 합니다. 둘 다 구성되면 정적으로 매핑된 FC 타겟은 구성된 이름을 갖습니다. 이 문서에서는 정적 매핑의 예를 제공합니다. 동적 매핑을 사용하면 iSCSI 호스트가 IPS 모듈에 연결될 때마다 새 FC N 포트가 생성되고 이 N 포트에 할당된 nWWN 및 pWWN이 다를 수 있습니다. IPS 모듈에 연결할 때마다 iSCSI 호스트에 대해 동일한 nWWN 및 pWWN을 가져오려면 고정 매핑 방법을 사용합니다. IPS 모듈에서 정적 매핑을 사용하여 이니시에이터의 pWWN 또는 nWWN을 기반으로 액세스 제어 및 LUN(Logical Unit Number) 매핑 및 마스킹 컨피그레이션이 있는 지능형 FC 스토리지 시스템에 액세스할 수 있습니다.

타겟이 광고되는 특정 IPS 포트 목록을 생성하고 이를 액세스할 수 있는 iSCSI 이니시에이터 노드 이름 목록을 생성하여 정적으로 매핑된 각 iSCSI 대상에 대한 액세스를 제어할 수 있습니다. FC 조닝 (zoning) 기반 액세스 제어 및 iSCSI 기반 액세스 제어는 iSCSI에 대한 액세스 제어를 제공하는 두 가지 메커니즘입니다. 두 메서드를 동시에 사용할 수 있습니다. 이 컨피그레이션에서는 특정 VSAN에 대해 기본 영역 지정이 허용됩니다. IPS 모듈은 iSCSI 노드 이름 기반 및 FC 조닝 기반 액세스 제어 목록을 모두 사용하여 iSCSI 검색 및 iSCSI 세션 생성 중에 액세스 제어를 적용합니다.

iSCSI 검색: iSCSI 호스트가 iSCSI 검색 세션을 생성하고 모든 iSCSI 대상에 대해 쿼리하면 IPS 모듈은 액세스 제어 정책에 따라 이 iSCSI 호스트가 액세스할 수 있는 iSCSI 대상 목록만 반환합니다.
iSCSI 세션 생성: IP 호스트가 iSCSI 세션을 시작하면 IPS 모듈은 지정된 iSCSI 대상(세션 로그인 요청)이 정적 매핑된 대상인지 확인하고, true인 경우 IP 호스트의 iSCSI 노드 이름이 대상에 액세스할 수 있는지 확인합니다. IP 호스트에 액세스 권한이 없으면 로그인이 거부됩니다.

그런 다음 IPS 모듈을 통해 이 IP 호스트에 대해 FC 가상 N 포트(N 포트가 이미 있을 수 있음)를 생성하고 IP 호스트에서 액세스하는 FC 대상 pWWN의 FCID에 대해 FC 이름 서버 쿼리를 수행합니다. IP 호스트 가상 N 포트의 pWWN을 이름 서버 쿼리의 요청자로 사용합니다. 따라서 이름 서버는 pWWN에 대해 영역 적용 쿼리를 수행하고 쿼리에 응답합니다. 이름 서버에서 FCID를 반환하면 iSCSI 세션이 수락됩니다. 그렇지 않으면 로그인 요청이 거부됩니다.

!--- The iSCSI driver discovery daemon process looks up each discovered !--- target in the /etc/iscsi.bindings file. If an entry exists in the file for the target, !--- the corresponding SCSI target ID is assigned to the target. If no entry !--- exists for the target, the smallest available SCSI target ID is assigned !--- and an entry is written to the /etc/iscsi.bindings file for this target.

!--- Note that the /etc/iscsi.bindings file permanently contains entries !--- for all iSCSI targets ever logged into from this host. If a target is !--- no longer available to a host, you can manually edit the file and remove !--- entries so that the obsolete target no longer consumes a SCSI target ID. !--- If you know the iSCSI target name of a target in advance, and you want !--- it to be assigned a particular SCSI target ID, you can add an entry !--- manually. You must stop the iSCSI driver before editing the !--- /etc/iscsi.bindings file. The maximum number of targets is 14.

!--- Enter [/]#/sbin/init.d/iscsi start to manually start the iSCSI driver.

!--- Enter [/]#/sbin/init.d/iscsi stop to manually stop the iSCSI driver.
