oracleasm icin direk disk kullanimi (udev ile, asmlib olmadan) ayarlanmasi

oncelikle multipath yapilandirmasi ve disk bolumleme islemi tamamlanmis olmali.

Kontrol yaptigimizda:

[root@rac02 ~]# ls /dev/mapper/
arch01    control   data02p1  fra02p1  mgmt01p1  ocr02p1         ocr-quorum02p1
arch01p1  data01    fra01     fra03    ocr01     ocr-quorum01    ol_rac02-root
arch02    data01p1  fra01p1   fra03p1  ocr01p1   ocr-quorum01p1  ol_rac02-swap
arch02p1  data02    fra02     mgmt01   ocr02     ocr-quorum02
[root@rac02 ~]#

 

yukaridaki gibi goruyorsak asagidaki gibi mpath-list dosyasi olusturuyoruz.

 

[root@rac01 ~]# cat mpath-list
arch01p1
arch02p1
data01p1
data02p1
fra01p1
fra02p1
fra03p1
mgmt01p1
ocr01p1
ocr02p1
ocr-quorum01p1
ocr-quorum02p1

Dosyamiz hazirsa asagidaki script ile udev kurallarini olusturabiliriz.

[root@rac01 ~]# cat udev-kurallarina-ekle.sh
#!/bin/bash

rm -f /tmp/99-oracle-asmdevices.rules
