案例：HP L2000下PDC以及GSP firmware升级（二）

penguinstorm

继上次更换GSP卡之后，客户继续来电，称日志中又开始间隔一天的出现之前报错信息。

故障分析：
GSP卡有两种类型，一种为A类，另一种为B类，目前就官方公布的最新版本分别是A.01.12（对应的文件名为PF_CPREGSPA0112.tar.gz），以及B.02.20（对应的文件名为PF_CCANGSPB0220.tar.gz）。客户之前报错机器L2000对应GSP firmware版本为B.02.04，现更换的GSP firmware版本为A.01.09，都为较低版本。根据日志故障所反映的情况来看，决定对PDC以及GSP firmware升级至最高版本。
注：客户L2000中PDC版本为41.39，目前最新版本为44.28，对应补丁名为PHSS_37205；要将B类GSP卡firmware升级至最高版本B.02.20，务必先将其升级至B.02.15。

故障解决过程：
1、vi /var/adm/syslog/syslog.log查看日志报错情况以及GSP卡状态；
2、shutdown –hy 0关机、下电，将之前换上A.01.09版本的GSP卡重新换回来（GSP卡版本为B.02.04）；
3、通过远程FTP将PDC更新补丁PHSS_37205以及GSP卡firmware两个微码B.02.15、B.02.20上传至/tmp/storm目录；
4、执行命令sh PHSS_37205后得到PHSS_37205.depot文件，swinstall –s /tmp/storm/PHSS_37205.dep
Ot对该补丁进行安装，安装完毕后重新启动机器；
5、机器自检完毕后，十秒中断处PDC版本进行自动更新，后重启；
6、根据以下步骤对GSP firmware进行更新：
* * * * * * * *  VERIFYING CURRENT REVISION OF FIRMWARE  * * * * * * * *

1. telnet into the GSP.
2. logon to the GSP.
3. Type ecf.
4. Type b.
5. Type he

                                  If the Revision number of the currently installed firmware is not
A.01.11 then install new firmware.

                                * * * * * * * * * *  UNPACKING THE FIRMWARE * * * * * * * * * * * * * *
1. FTP "PF_CPREGSPA0112.tar.gz" to an empty directory.
  2. Use the "gunzip" to unzip the patch.
# gunzip PF_CPREGSPA0112.tar.gz
3. Use the "tar" command to extract the firmware files
#  tar -xvf PF_CPREGSPA0112.tar
x APPLICATION.ROM, 1368392 bytes, 2673 tape blocks
x BOOTSTRAP.ROM, 131072 bytes, 256 tape blocks
x upgrade.cnf, 127 bytes, 1 tape blocks
4.  Verify the checksum of the file "APPLICATION.ROM" using the "cksum" command.  Results of the command should be equal to "1602442620 1368392 APPLICATION.ROM".
5.  Verify the checksum of the file "BOOTSTRAP.ROM" using the "cksum" command.  Results of the command should be equal to "1366608320 131072 BOOTSTRAP.ROM".
6.  Verify the checksum of the file "upgrade.cnf" using the "cksum" command.  Results of the command should be equal to "1542976150 127 upgrade.cnf".

                              * * * * * * * * * * * FIRMWARE UPDATE PROCEDURE  * * * * * * * * * *
                            To update the firmware on the GSP, perform the following steps:
                            FTP the files to a system with the core I/O lan on the same subnet as the GSP
                            FTP the firmware files to a system accessible from the GSP to be updated.
1.   Access the GSP using the ctrl+b command from the local console keyboard.
2.   Ping the LAN where the GSP files are located via the XD command item #3 (LAN access PING)
GSP> XD
XD
Non destructive tests :
1. Parameters checksum
2. I2C access (get Power Monitor status)
3. LAN access (PING)
4. Modem selftests

Type R to reset the GSP or Q to quit the diagnostic menu.
->Choice: 3
Enter IP Address:  Enter the IP address of the system where the firmware files are located.
This test must pass on the server being used to supply the firmware files.
3.   Reset the GSP via the XD command (use the R option).
This will free up any unallocated memory for the GSP update.
GSP> XD
XD
Non destructive tests :
1. Parameters checksum
2. I2C access (get Power Monitor status)
3. LAN access (PING)
4. Modem selftests

Type R to reset the GSP or Q to quit the diagnostic menu.
-> Choice: r
Wait 1 minute for the memory to free up.

4.   Select the GSP command XU. This command activates the upgrade mode.
GSP> xu
XU
This command activates the upgrade mode. All connections will be closed, the network will be stopped, the session will be aborted and the modem connection will be dropped.
Please, confirm your intention to activate the upgrade mode (Y/[N]) : y
Enter source system IP address: Enter the IP address of the system where the firmware files are located.

Enter file path: The path on your system with firmware files.
Do you wish to use the default login: anonymous /GSP@hp.com (Y/[N]): n
-> GSP firmware upgrade in progress..
-> GSP firmware upgrade complete - GSP will now reset..

                                       * * * * * * * * * * * * * *  END OF UPDATE  * * * * * * * * * * * * * *
7,待GSP firmware更新完毕，重启系统并查看日志，swlist |grep PHSS_37205检查PDC补丁是否打上，ctrl+b进入GSP，he观察GSP firmware版本是否已经更新至B.02.20；
8，签写服务报告、收拾现场。
