10、K Scanning the system for Oracle ASMLib disks: OK rootrac1 rpm# 2.3 创建ASM磁盘If you intend to use IDE, SCSI, or RAID devices in the Oracle ASM disk group, then follow these steps:If necessary, install or configure the shared disk devices that you intend to use for the disk group and restart the system

11、.To identify the device name for the disks to use, enter the following command:Depending on the type of disk, the device name can vary:Disk TypeDevice Name FormatDescriptionIDE disk/dev/hdxnIn this example, x is a letter that identifies the IDE disk and n is the partition number. For example, /dev/h

12、da is the first disk on the first IDE bus.SCSI disk/dev/sdxnIn this example, x is a letter that identifies the SCSI disk and n is the partition number. For example, /dev/sda is the first disk on the first SCSI bus.To include devices in a disk group, you can specify either whole-drive device names or

13、 partition device names.Note:Oracle recommends that you create a single whole-disk partition on each disk.Use either fdisk or parted to create a single whole-disk partition on the disk devices.Enter a command similar to the following to mark a disk as an Oracle ASM disk:# /usr/sbin/oracleasm created

14、isk DISK1 /dev/sdb1In this example, DISK1 is the name you assign to the disk.Note:The disk names that you specify can contain uppercase letters, numbers, and the underscore character. They must start with an uppercase letter. If you are using a multi-pathing disk driver with Oracle ASM, then make su

15、re that you specify the correct logical device name for the disk.To make the disk available on the other nodes in the cluster, enter the following command as root on each node:# /usr/sbin/oracleasm scandisksThis command identifies shared disks attached to the node that are marked as Oracle ASM disks
