先通过lsblk来查看集群两端磁盘是否扩容成功
lsblk -a
查看自己两边磁盘UUID是否相同(for i in 后面为磁盘sd后字母名)
for i in x y z aa ab ac ad ae
do
echo "KERNEL==\"sd*\", SUBSYSTEM==\"block\", PROGRAM==\"/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", SYMLINK=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""
done
mpath查看自己两边磁盘UUID是否相同
for i in f
do
echo "KERNEL==\"dm-*\", SUBSYSTEM==\"block\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/mapper/mpath$i`\""
done
两边添加绑定文件
vi /etc/udev/rules.d/99-oracle-asmdevices.rulesKERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3604338910032ebd46348494100000350", SYMLINK="asmdat2", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3604338910032ebd4109017e200000209", SYMLINK="asm-diski", OWNER="grid", GROUP="asmadmin", MODE="0660"
两边编辑绑定文件后，依次执行以下命令
/sbin/udevadm control --reload
/sbin/udevadm trigger --type=devices --action=change
执行后检查两边的磁盘权限属组情况
su - grid
crsctl stat res -t ll /dev/sd*
ll /dev/asm* --注意权限&属组ll /dev/sd*
