主机&阵列常用命令
阵列：阵列有两种访问方式：串口、网络。
一般第一次配置是通过串口，然后可以给阵列配置IP，就可以通过网络TELNET访问了。
常用机型命令：
T3、SE6120: 此两种机型命令基本一致，常用的是fru和vol命令。
fru list是阵列中各fru部件的列表。
fru stat是阵列中各fru部件的状态列表。
vol list是阵列上所有卷的名称、容量、raid级别、卷的组成、卷的standby盘。
vol stat是卷的状态、卷中各盘的状态。
fru——现场可替换单元(包括控制器、盘、互连卡、电源模块、主板)
下面是正常的阵列系统情况：

SE3310、SE3510阵列是一种类似图形化的访问界面，可以看到阵列中各部件的状态；做的卷、分区状态；划分的LUN等。
根据图形化菜单选择即可，不需要命令。
主机:
Sun公司的主机虽然有很多机型，但其安装的操作系统都是一样的，现在比较常用的是Solaris 8和9；主板的NVRAM芯片上包含了在操作系统脱机的情况下察看系统状态和进行配置的系统OBP，OBP的版本也是不断升级的，版本越高，支持的功能也就越多；还有一些机型可以通过系统中安装的ALOM或RSC卡配置IP后，进行远程控制，可以实现远程登录、重启、开关机等操作。
常用命令：
操作系统中：
操作系统的日志是非常重要的检查系统状态的工具，它们是位于/var/adm目录下的messages文件。一般来讲，当messages文件中含有ERROR、WARNING等信息时就需要注意了。
如下面这条信息：
Apr 14 09:02:57 ruiyi scsi: WARNING: /pci@1f,4000/scsi@3/sd@1,0 (sd1):

Apr 14 09:02:57 ruiyi scsi: ASC: 0x5d (), ASCQ: 0x32, FRU: 0x32
这是一条WARNING信息，标明了物理地址/pci@1f,4000/scsi@3/sd@1,0上的设备出现错误，经过检查，这个设备是一块scsi硬盘，它出现了读写错误，这个时候我们就应该更换硬盘了。
如下面的信息：

这条信息为CPU检测到了内存错误，一般可定位为内存问题，通过信息标明的内存编号可确定是哪一块内存；但有时可能会是CPU本身的问题，可以根据信息的具体提示和经验进行判断。
有时系统里会有一些不会导致系统出问题的WARNING信息，如
WARNING forceload of misc/md_trans failed
WARNING forceload of misc/md_raid failed
WARNING forceload of misc/md_hotspares failed
WARNING forceload of misc/md_sp failed
Mar 20 12:33:12 jsun-server1 syslogd: line 24: WARNING: loghost could not be resolved
这是一些软件没有配置完成、或是系统配置文件不完整所导致的，可根据经验修正，使它们不再出现。

上面为一台F6800系统的系统信息，从中可以看到系统中所有的配置情况：CPU、内存、I/O部件、硬件指示灯状态等。通过这些信息和messages日志文件的内容我们可以比较准确地定位问题。
硬盘检查工具
当硬盘出现问题时，一般我们可以在messages信息中看到提示，我们也可以使用format命令来比较全面地检查硬盘。
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t1d0
/pci@1f,4000/scsi@3/sd@1,0

backup - search for backup labels
verify - read and display labels
save - save new disk/partition definitions
inquiry - show vendor, product and revision
volname - set 8-character volume name
! - execute , then return

format>
在format命令里选择硬盘后，我们可以看到很多对硬盘进行操作的命令：改变分区、对硬盘进行读写分析、察看错误块等。对硬盘的操作一般由系统管理员来完成，非超级用户不能运行format命令。
OBP参数设置
进入OBP环境就是一般我们所说的ok状态，此时操作系统尚未启动，我们可以对系统启动参数进行各种设置，包括设置自检类型、定位输入输出、选择启动设备、察看系统硬件等。
printenv是察看参数设置值，setenv是设置参数值，是OBP中最常用的两个命令。
SC(系统控制)是一项比较实用的功能，提供了一个包含较多实用命令的操作环境，可以对系统进行远程控制。但这项功能需要硬件的支持，需要系统中安装有ALOM或RSC卡，第一次配置还是使用串口，然后可以对远程控制卡配置IP地址，以后就可以通过网络TELNET登录进入系统控制环境了，可以实现远程开关机和系统操作的一系列功能，完全不需要人到现场。
