HP MSA2012SA 磁盘阵列配置说明说明：可以先安装HP 服务器的操作系统，等安装完了以后再配置磁阵；1、安装好服务器的操作系统；该安装的包都安装上；2、磁盘阵列上架，加电，SAS 线不用接服务器；等磁阵自检后(估计2-3分钟左右)，在进行下一步操作； （所有磁盘指示灯全部闪烁后，又回到全部熄灭状态）3、准备网线，连接到磁阵后面的控制器上，（两个控制器皆可），控制器A 默认地址为10.0.0.2 ，控制器A 默认地址为10.0.0.3， PC或者笔记本配置地址可以是10.0.0.5 ，掩码255.255.255.0 ，网关不用设置，假设你直连到控制器A。打开IE浏览器

Exception :java.lang.UnsatisfiedLinkError:/usr/java/j2sdk1.4.2_06/jre/lib/i386/libawt.so: libXt.so.6: cannot open shared object file: No such file or directory这个错误是也是由于缺少系统安装包造成的，只需安装XFree86-libs包即可，这个安装包可以在系统光盘中找到。 在上面两个错误如果出现在redhat as5版本中，解决如下：在RHEL5中上面的包被libXp所取代了，因此rpm -ivh libXp-1.0.0-8.i386.rpm将包打上后问题即可解决。libXp-1.0.0-8.1.el5.i386.rpm[@more@]

1、安装操作系统，建议分10G root如果是虚拟机，建议分1G的内存空间，磁盘空间为30G官方文档在AS4的推荐参数如下，同时注明若默认参数大于推荐值，则不要修改。semmsl 250semmns 32000semopm 100semmni 128shmmax Half the size of physical memory (in bytes)shmmni 4096shmall 2097152file-max 65536ip_local_port_range Minimum: 1024 Maximum:65000rmem_default 1048576rmem_max 1048576wmem_default 262144wmem_max 262144实际发现as5在参数上大多已超过推荐值实例如下：/etc/sysctl.conf.文件net.ipv4.ip_forward = 0net.ipv4.conf.
