綁定對象可以為磁盤 也可為分區(qū)(格式化后的磁盤)

識別磁盤(/sbin/scsi_id)?

• Oracle Linux 5用如下腳本：

#！/bin/sh for i in b c d e f g do echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id -g -u -s /block/$parent", RESULT==\"`/sbin/scsi_id /block/sd$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"" done

• Oracle Linux 6用如下腳本(未驗證)：

#！/bin/sh for i in b c d e f g 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

UDEV配置文件

重要：每個配置文件一行為一條規(guī)則，并且，（逗號）與下一個關(guān)鍵詞之間有空格

• Oracle Linux 5用如下參數(shù)

添加SCSI設(shè)備信任關(guān)系

編輯"/etc/scsi_id.config" 文件配置SCSI設(shè)備信任關(guān)系:?options=-g

[root@ncdb2 dev]# vi /etc/scsi_id.config # # scsi_id configuration # # lower or upper case has no affect on the left side. Quotes (") are # required for spaces in values. Model is the same as the SCSI # INQUIRY product identification field. Per the SCSI INQUIRY, the vendor # is limited to 8 bytes, model to 16 bytes. # # The first matching line found is used. Short matches match longer ones, # if you do not want such a match space fill the extra bytes. If no model # is specified, only the vendor string need match. # # options=<any scsi_id command line options> # vendor=string[,model=string],options=<per-device scsi_id options># some libata drives require vpd page 0x80 vendor="ATA",options=-p 0x80options=-g
