mds9124_passwordRecovery_howto

关闭所有连接该光交的应用服务。

I. 通过串口线连接至EMC MDS9124管理口，打开HyperTerminal/Minicom程序，设置连接如下 == Bits per second: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow control: None (注：如果是MDS9500系列则把Bits设置为38400)

I. 由于密码已忘记，手动按电源重启EMC光纤交换机。 3、交换机重启进入SANOS时，按住Ctrl+]键使交换机进入到boot模式

switch(boot)#

4、切换到配制模式，并更改密码。 switch(boot)# configure terminal switch(bootconfig)# adminpassword PASSWORD switch(bootconfig)# exit

5、加载启动映像进入正常模式。 switch(boot)# load bootflash:SANIOS.img

6、保存配制信息即完成，登录使用新密码测试。 switch# copy runningconfig startupconfig

最后：应用服务器主机重新扫描磁盘，识别正常后，开启相应服务即可。 cfgmgr -v lsdev -Ccdisk

Reboot SP

1 - make sure all your servers have connectivity to both SPs, to avoid disruption when you reboot a SP.

2 - verify the load on both SPs, using Navisphere Analyzer, try to do the reboot when the peer SP has low load.

3 - reboot the SP.

HOW TO: Restart Unisphere Management Server

Restarting the Management Services should clear up any Unisphere UI issues or any discrepancies between Unisphere UI and Unisphere CLI.

Restarting the Management Services is a non disruptive task and can be perform without a downtime.

1. Open a web browser and go to https://SP_IP_or_FQDN/setup, where ‘SP_IP_or_FQDN’ is Storage Processor’s IP address or the host name

2. Login with ‘sysadmin’ user account and password or any other account with administrator privileges

4. Confirm the Management Services Restart and wait until the restart has completed. Note, this can take up to 10 minutes.

5. Once the first Service Processor reboot has occurred and you are able to log back into that Service Processors’ Web Services then proceed to the second Service Processor.

This should clear up any Unisphere GUI issues or incorrect reporting of information on the Host Agent’s page.
