간단한건데 안쓰다보면 이건가 저건가하고 아리까리 해진다.

그래서 간단하게 정리하고 넘어가겠다.





전반적인 XLV를 구성한 시스템 구조이다.

controller 2 에 8개의 디스크로 구성되어 있는것을 XLV 로 Stripe 시키면

Newly created objects will be written to disk.
Is this what you want?(yes) yes
Invoking xlv_assemble


xlv_mgr
xlv_mgr> show -verbose all
xlv_mgr> exit
mkfs /dev/xlv/lv0
mkfs /dev/xlv/lv1

lv0 과 lv1 을 이제 마운트 해주면 된다.


* 설명하기 귀찮아서 패스하려다가 간단하게 언급하고 넘어가겠다. *
* XLV 로 Stripe 시킬때 중요한것은 파티션 0 과 1 만 만들어주면 되기때문에
아래의 방법대로 안하고 다른 방법으로 만들어줘도 잘 돌아간다. *





위에 그림에서 보면 알수 있듯이 XLV 는 Striping 시켜놨을때 0 과 1 로 2개의 파티션으로 묶어진다.

당연히 fx 작업을 할때 0 과 1 의 파티션을 만들어 주어야만 묶어진다는 말이다.

예를 들어서 disk 4 (SCSI ID 4) on SCSI controller 1

fx 로 파티션을 만들어 줄때

# fx -x
fx version 6.3, Nov 26, 1996
fx: "device-name" = (dksc)
fx: ctlr# = (0) 1
fx: drive# = (1) 4
fx: lun# = (0)
...opening dksc(1,4,0)
...controller test...OK
Scsi drive type == AVID DGHS18U 0210

위와 같이 파티션을 만들어준후 수정해주면 되겠다.
