今天接到CTC的urgent call，说E450的硬盘找不到了。
1、首先检测local硬盘(即标配带的4个)，发现散热片在上面，拆除散热片后，这4块硬盘找到了。probe-scsi-all看到：
/pci@6,4000/scsi@4,1

/pci@6,4000/scsi@4

/pci@1f,4000/scsi@2
Target 6
  Unit 0 Removable Read Only device TOSHIBA XM6201TASUN32XCD1103

/pci@1f,4000/scsi@3
Target 0
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 1
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 2
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 3
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A

2、因为应该出现DISK的/pci@6,4000/scsi@4,1和/pci@6,4000/scsi@4都没有显示DISK，所以检查E450的扩展ctrl卡，发现AB线序接错了(应该是A对应u，B对应d)，调好后重新启动，probe-scsi-all显示如下：
/pci@6,4000/scsi@4,1
Target 0
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 1
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A

/pci@6,4000/scsi@4
Target 0
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 1
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A

/pci@1f,4000/scsi@2
Target 6
  Unit 0 Removable Read Only device TOSHIBA XM6201TASUN32XCD1103

/pci@1f,4000/scsi@3
Target 0
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 1
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 2
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A
Target 3
  Unit 0 Disk    SEAGATE ST39103LCSUN9.0G034A

3、(关键)之后关上机箱，启动机器，在OS里面使用format，还是不能检测到后来的4块扩展硬盘：
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
   0. c0t0d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@0,0
   1. c0t1d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@1,0
   2. c0t2d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@2,0
   3. c0t3d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@3,0

因为能够probe到，所以再次开箱，发现内部连接有多块6541(差分SCSI卡)，于是进入OBP设置：
OK >; setenv disk-led-assoc 0 2
reset-all后进入系统format：

# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
   0. c0t0d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@0,0
   1. c0t1d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@1,0
   2. c0t2d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@2,0
   3. c0t3d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@1f,4000/scsi@3/sd@3,0
   4. c10t0d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@6,4000/scsi@4/sd@0,0
   5. c10t1d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@6,4000/scsi@4/sd@1,0
   6. c11t0d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@6,4000/scsi@4,1/sd@0,0
   7. c11t1d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>;
      /pci@6,4000/scsi@4,1/sd@1,0
Specify disk (enter its number):

完成。

关于disk-led-assoc的用法：

OK >; setenv disk-led-assoc 0 x y

      x is an integer between 1 and 10 identifying the rear panel PCI slot
      number where the lower UltraSCSI controller is installed
      y is an integer between 1 and 10 identifying the rear panel PCI slot
      number where the upper UltraSCSI controller is installed

由于我使用的是6541，所以没有y。x和y都在一块卡上实现。

希望大家今后遇到这种事能少开一次机箱。。
