Fibre Channel QLA2340 a pripojeni disku

[Zdenek SUTR Kaminski]

Dobry den,

  prisel jsem jako slepy k houslim k FiberChannel karte QLA2340 v jednom 
serveru. Tusim, ze by mela byt jednoportova (server je daleko a tohle mi 
rikal __ten__ pan) a mela by byt pripojena do switche a z nej by mely vest 
dve cesty k jednomu diskovemu poli. Tam by mel byt nazonovany disk, ovsem 
ja nevim, jak se k nemu dostat.

  Navic tak nejak tusim, ze budu muset zprovoznit neco, co bude hlidat, po 
ktere ceste se leze k tomu disku primarne a po ktere ceste se k nemu leze, 
kdyz ta aktualne pouzivana vypadne.

  Nakonec na tom budu muset zprovoznit GFS (coz umim a vim jak na to), 
protoze ten disk v poli pak bude nazonovan dalsimu stroji.

Rad bych Vas poprosil o dve veci.

- moznou pomoc pri zprovozneni. Myslim, ze jsem totiz velmi blizko (par 
prikazu), nicmene, nevim jak. Po natazenem modulu qla2300 nevim, jak se 
dopracuji k zarizeni /dev/sda

- nasmerovani k patricne dokumentaci k problematice veci. Budu to 
asi spravovat, takze o tom budu muset neco vedet. Co mam vubec hledat.



Pouzivam RHEL 4 ES - posledni updaty

V modprobe.conf mam ohledne scsi toto:
--------------------------------------
alias scsi_hostadapter qla2300
alias scsi_mod max_luns=128


Dale jsem vytvoril novy initrd:
-------------------------------
mkinitrd -f -v /boot/initrd-2.6.9-42.0.3.EL.img 2.6.9-42.0.3.EL

Po natazeni modulu qla2300 (tez restartu stroje) vidim v dmesg:

Otazka za 100tis: Jak se ted doberu /dev/sda?





Diky za nasmerovani k patricne dokumentaci a za pripadnou pomoc (to abych 
mohl na tom stroji bastlit hned).
