请教各位一个问题:最近要给客户一台S85(P680)安装AIX 5.3,看了官方上的文档,firmware需要升级到至少20040716,客户现在跑的4.3操作系统.看了一下firmware下载出的DESC,有几个疑问:
1.升级前执行:
lscfg -vp | grep -p alterable
This command will produce a system configuration report similar to the following.
System Firmware VPD:
ROM Level.(alterable).......20030731 (B) 20030731 (A) <= System FW levels
Version.....................RS6K
System Info Specific.(YL)...U0.1-P1-X1
Physical Location: U0.1-P1-X1/Y1
Service Processor Firmware VPD:
ROM Level.(alterable).......20030731 (B) 20030731 (A)
Version.....................RS6K
System Info Specific.(YL)...U0.1-P1-X1/Y2
Physical Location: U0.1-P1-X1/Y2
按照我的理解这里的A与B,应该类似于P5系列用lsmcode所看出的临时和永久firmware,但我想知道这里的A与B,哪一个是临时启动所用的,哪一个是永久的?
如果没有执行Promot操作的话,如何用原先的那个永久的回退到升级前状态,如何操作?
升级完之后,如果再次执行lscfg -vp | grep -p alterable This command will produce a system configuration report containing sections similar to the following. System Firmware VPD:
ROM Level.(alterable).......20040716 (B) 20030731 (A)
Version.....................RS6K
System Info Specific.(YL)...U0.1-P1-X1/Y1
Physical Location: U0.1-P1-X1/Y1
Service Processor Firmware VPD:
ROM Level.(alterable).......20040628 (B) 20030731 (A)
Version.....................RS6K
System Info Specific.(YL)...U0.1-P1-X1/Y2
Physical Location: U0.1-P1-X1/Y2看上面的结果,应该B是启动所用的,也就是所谓临时的,A是原先永久的。这里如何永久提交临时的firmware?应该是所谓的Promot操作吧。另外我看DESC里面还有几个不解的地方:文档中说到“The server normally runs IPL Type A. New firmware updates are stored in IPL Type B until they are promoted. Once promotion takes place, the two IPL types are identical.”既然说通常用A启动,但是升级后从以上显示来看系统用的是B呀,不知道怎么理解?DESC最后提到执行promot操作时,简单的说到了利用下载的另外一个promote.img 文件,但怎么利用这个文件永久提交临时firmware呀? |
