1) 下载补丁 136927-04.zip, 升级Firmware到6.6.5,由于环境具备,所以用的ftp server的方式升级,先配好Net mgt口的管理ip,然后把此补丁放到一个ftpserver上面。
sc> poweroff
Are you sure you want to power off the system [y/n]? y
sc>
SC Alert: SC Request to Power Off Host.
SC Alert: Host system has shut down.
sc>
1) Make sure that your virtual keyswitch setting is not in the LOCKED
position.
You can check the setting from the System Controller CLI with the
following command:
sc> showkeyswitch
If the virtual key switch is in LOCKED position you can change that
with the following command:
sc> setkeyswitch -y normal
2) At the sc> prompt, type the flashupdate command.
Substitute the IP address of the FTP server mentioned above for
"ipaddr", and the path name to the image on that server for
"pathname".
sc> flashupdate -s -f
3) When prompted, type your username and password. The username and
password are based on your UNIX or LDAP user name and password of the
FTP server specified by "-s ipaddr", and not your ALOM username and
password. After you type your user name and password, the download
process continues. As the download process progresses, a series of
periods appear across your screen.
SC Alert: System poweron is disabled.
Username: user
Password: ******
.......................
When the download process is finished, ALOM displays the message:
Update complete. Reset device to use new software.
4) The Sun System Firmware has now been updated. For the system to use
the new firmware you must reset the System Controller.
Type the resetsc command to reset ALOM.
sc> resetsc
User Requested SC Shutdown
5) sc> poweron -c
2) 想用1.0.3,如果条件允许重装系统的话,一定要直接下载安装08年5月版的solaris10,不然打补丁一环扣一环,麻烦的要命,最后明明说补丁安装完成,但是关键的ldom组件都没装上,不知道补丁补哪里去了。
笔记:
性能为先的思想划分原则是每个逻辑域的vcpu个数是4的整数倍,即core的个数,因为每个core里面的线程如果被分到不同的域里面,会产生对该core的一级缓存的竞争而性能下降
有数据库的应用,则再建立一个service domain,直接对磁盘进行I/O,否则通过虚拟磁盘性能下降了不少。
逻辑域的cpu个数可以动态在线修改,其他devices则需要重启生效。
