这有不少是做SUN维护的吧。高手们很多,谈谈光纤硬盘的DD及映像。
听说光纤硬盘DD或映像后拔出原盘,用从盘启动会有问题。小第今天碰到神州数码的人问了一下,说用命令改什么WW?的也没明白,论坛上搜了一下只有“凤凰”提到过这一问题其他就没了。高手们对这一问题是怎么做的能够告诉我吗?
想必也有不少朋友想知道。
SCSI的硬盘DD后从盘插入fsck 从盘后reboot就可。(U60上测试通过)
SCSI的硬盘映像后从盘插入进入OK下从物理路径启动即可,其他不用改。例:
ok boot /pci@1f,4000/scsi@3,0/disk@0,0
光纤硬盘DD及映像后如何修改???

应该也是查找的从盘的启动路径进行BOOT的吧,但是应该修改一下/etc/vfstab吧。您说?

大家支持一下吧。

solarissystem 回复于:2003-10-28 21:48:15
做完后把从盘插到主盘的位置要怎样才能成功启动?改那些配置?

FC的硬盘没做过,是不是还得加个installboot

diag 回复于:2003-10-29 09:27:53
edit vfstab ..

OK > BOOT DISK

我来说一下:
首先dd完成后,将目标盘mount,并将目标盘上的一个文档path_to_inst删除。
然后将目标盘放入引导盘位置(这样就无需改vfatab),使用boot -ai来进行引导并重建path_to_inst

光纤盘好象不是改vfstab这么简单吧。(听说光纤盘比较特别,现在用光纤硬盘的机器多了,问题也出来了。如:280 480 880 等)
有做过的高手请顶一下。谢谢

以前讨论过,据说能够

但是都不推荐

procrus 回复于:2003-10-29 10:45:37
直接dd就能够了

solarissystem 回复于:2003-10-29 10:48:13
这么多星的蜘蛛将军办法应该很多,来给个答案。(巴顿将军也只有4颗星)

solarissystem 回复于:2003-10-29 10:51:43
procrus 您说的是光纤硬盘吗?换位后可直接启动?原盘拔出后可直接启动吗?您用什么机器试的?

20-80那本书上说了不建议dd克隆用在FC-AL盘上

solarissystem 回复于:2003-10-29 11:17:49
FD硬盘映像后换位哪?怎么做?

race 回复于:2003-10-29 11:25:24
直接把原盘拔下来,把新盘换上去,OK>boot -r

race 回复于:2003-10-29 11:28:24
克隆更有别的方法,能够去参考

SYNOPSIS: Recovering from a failed FCAL boot disk

DETAIL DESCRIPTION:

A host that boots from a non-mirrored FCAL disk (either an A5000 or the E3500

internal disks) will have to overcome the hard-coded World Wide Number (WWN)

that each of these disks uses as an integral part of their device path.



On failure of the boot disk the systems administrator must ensure that this

WWN is correctly updated throughout the system to ensure it will reboot.



SOLUTION SUMMARY:

Procedure :



1) The boot disk fails and is replaced by another disk with a different

WWN.



2) Boot the system into single user from the cdrom or network.



3) Label the replacement disk to match the slices from the failed one.



4) Create filesystems on all the slices to be restored.



5) Mount the root filesystem and restore the data from backups.



6) Install the boot block onto the recovered root slice using the

"installboot" command.



7) With root mounted under "/a" run the following commands to re-build

the devices tree :



drvconfig -r /a/devices -p /a/etc/path_to_inst



cd /devices

find . -print | cpio -pduVm /a/devices



disks -r /a

devlinks -r /a



NOTE: It is currently necessary to use both "drvconfig" and "find | cpio" due

to bugid 4161768, drvconfig does not work properly with socal disks.



8) Configure the "boot-device" parameter in the EEPROM using the

"luxadm set_boot_dev /dev/dsk/{root slice entry}" command.



9) Restore the other filesystems on that disk, or comment out the

entries for them from /a/etc/vfstab. At least you must have all the

Solaris filesystems (root, /var, /usr, /opt, etc.) recovered.
