Solaris SPARC 机器一个boot issue的案例

在做一个数据库server的操作时候，遇到一个boot issue。正常处理完之后需要重启server，init  6之后，等了许久，机器就是没有起来。登陆到console里看机器状态
发现机器处于OK模式，说明server没有问题，可以正常加电。但是为什么不能从磁盘启动呢？

1）进入console输入boot启动，出现如下output，启动失败，退到ok模式

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y
Serial console started.  To stop, type #.
{0} ok
{0} ok
{0} ok

2）输入boot disk，一样，无法启动

3）只能先查看下机器磁盘有几块，使用devalias命令

发现2块盘做了mirror，

{0} ok devalias
rootmirror               /pci@0/pci@0/pci@2/scsi@0/disk@1,0
rootdisk                 /pci@0/pci@0/pci@2/scsi@0/disk@0,0
ttya                     /ebus@c0/serial@0,ca0000
nvram                    /virtual-devices/nvram@3

disk5                    /pci@0/pci@0/pci@2/scsi@0/disk@5
disk4                    /pci@0/pci@0/pci@2/scsi@0/disk@4
disk3                    /pci@0/pci@0/pci@2/scsi@0/disk@3

scsi                     /pci@0/pci@0/pci@2/scsi@0
virtual-console          /virtual-devices/console@1

4）于是ok模式下，先从rootdisk启动，
输入 boot rootdisk，发现报错，无法启动

{0} ok boot rootdisk
