3. udev识别出新增加的磁盘
(1) udev设备生成脚本,用于识别出新增加的脚本
for i in b c d e f g h i j;
do
echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""
done
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="14f504e46494c4552395a55706766

(2) 将以上内容asm-diskj一行增加到以下文件中,在node1,node2上同时增加。
# vi /etc/udev/rules.d/99-Oracle-asmdevices.rules
4. 查看并添加集群ASM磁盘卷组
(1) 查看卷组情况
[root@node1 ~]# su - grid
[grid@node1 ~]$ sqlplus / as sysasm
SQL> set pagesize 999;
SQL> set linesize 200;
SQL> col name format a20;
SQL> select group_number,name,TOTAL_MB, FREE_MB from v$asm_diskgroup;
(2) node1上查看udev设备,并查看新增加的磁盘被识别到了没有。两边都需要确认。
SQL> col name format a20;
SQL> col path format a20;
SQL> select name,path,mode_status,state,disk_number,failgroup from v$asm_disk;
(3) node2上查看udev设备,并查看新增加的磁盘被识别到了没有.
(4) 增加新的磁盘到DATA asm卷组。
SQL>
SQL> alter diskgroup DATA add disk '/dev/asm-diskj' rebalance power 1;
Diskgroup altered.
SQL>
(5) 查看ASM卷组平衡过程,平衡完后,该内容为空。
