SUN E250升级OBP的问题
有一台练手的E250，试着升级OBP报错：Can't open /flash-update-250-latest
升级步骤：
1.cp flash-update-250-latest /
2.chmod 755 /flash-update*
3.ls -l
-rwxr-xr-x 1 root other 1441145 Apr6 11:20 flash-update-250-latest
4. halt
5.OK>boot disk /flash-update-250-latest
Can't open /flash-update-250-latest
然后boot disk就不能正常进solaris 10了，会报trap 3e的错误，需要reset后，重新boot disk才能正常进系统
重新下载了其他版本的OBP也是同样状况
之前在V440上同样的步骤升级OPB成功，跟这台的区别是V440的OS是Solaris 8， root disk是单盘
而这台E250的OS 是solaris 10， root disk是两块盘用SVM做的Mirror
怀疑是mirror的原因，是不是不能用mirrored disk来升级OBP？ 回复 1# ragecf
E250升级PROM，先得跳线，否则不让升级。:em27: 建议LZ好好看看升级补丁的README。 东方蜘蛛 发表于 2012-04-06 14:33 static/image/common/back.gif
建议LZ好好看看升级补丁的README。
c) Jumper J2704 is factory-set so that the flash PROM is write-enabled.
There is no need to switch the jumper before flash updating; however,
you must ensure that the keyswitch is in the Power-on or Diagnostics
position.When the key switch is in the locked position the flash
PROM is write protected. 财版 发表于 2012-04-06 14:26 static/image/common/back.gif

应该不会有人重新跳过，一会检查一下 蜘蛛还在努力的发帖，回帖支持下@ 回复 2# 财版
刚才打开机器找到跳线，原先短接2,3针，换到1,2针短接，还是这样
手上另外有一台E250，拿了一块solaris 8的单盘升级OBP，每次boot disk /flash-update-250-latest，机器直接重启。。。 回复 7# ragecf
請問可以正常開機嗎?机器是否直接重启?
另外，針對 TRAP 3E 問題
Cause
Ultra system fails to boot with TRAP 3E. The system sometimes also displays bad magic number errors.
This is caused by a bad superblock on the boot disk. Which, in turn, could have beee caused by a SCSI configuration problem.

/转了几圈就重启了。
但是如果直接boot disk, 是可以正常进系统的
