AIX cloning system

Environment, P630 two units, one can not boot, a normal startup, hardware information:

P630-1 (Unable to boot) p630-2 (boot hdisk7)

Solt Solt

1 HDISK6 1

2 Hdisk5 (BAD) 2

3 3 Hdisk5

4 HDISK8 4 Hdisk7

There are 3 mirror on machine number 2nd, so take the demolition first.

2#UNMIRRORVG ROOTVG

2#lsvg-l ROOTVG can be viewed, is a copy.

2#lspv-l Hdisk1 (because the front desk backstage hdisk number is not unified, 7=1;5=7)

The discovery has been empty hdisk1, OK, now start cloning

First, unplug the hard drive from the machine and plug it on machine number 2nd.

CFGMGR-V identification Hardware,

Upon completion, LSPV saw an extra hdisk8 to

Add identification to HDISK8

Chdev-l hdisk8-a Pv=yes

Now LSPV can see a string of very long character codes,

Perform:

Alt_disk_install-co Hdisk8 started cloning, P630 performance under the lack of only about 660K per second, so more than 20 g of things, I test for 2 hours ... It's really drunk. (Of course, this is something)

Enter after, had intended to eat something, left when turned a look, prompted hard disk space.

?????

Lsvg-p ROOTVG Look,

Well, the results come out, there are three physical devices disk Hdisk7 Hdisk8 Hdisk1 hdisk0

What's going on, Lspv-l Hdisk0

Find this hdisk0 below a root directory '/'

Lsvg-p ROOTVG show there are 4 PP, but it is missing state, estimated cloning time, the System Bar 4 pp also counted in, (just speculation, I was a two knife, no one taught me.) So the hint is not enough space.

Then pull out a plate from machine number 1th (identified as 6), as above, cfgmgr-v chdev-l hdisk6-a Pv=yes

Start cloning again:

Alt_disk_install-co hdisk6 HDISK8

After waiting 2 hours, finally completed, but the key now comes, after cloning is complete, you can only unplug the cloned disk, it is important to note that after cloning the 2nd machine startup item has changed to HDISK6, so, you need to operate:

Bootlist-m normal Hdisk7 (previously forgot to explain, 2 good Machine guide is originally HDISK7)

For the sake of insurance, bosboot-a one more.

When I finished, I turned off the No. 2nd machine, began to pull out two hard drives, (2nd machine normal start), unfortunate things happened, IBM led panel display e94a, hint description, file system corruption ...

Now, this is what the scene looks like.

No. 1th, number 2nd.

Solt Solt

None None

None None

Hdisk8 HDISK5

HDISK6 Hdisk7

Thinking about it, it feels like there's a place that might be wrong,

Alt_disk_install-co hdisk6 HDISK8

The order seems a bit problematic, after a long tangle .... Because the file is only a few 4 pp so the copy, the 4 pp absolutely do not come in, so 8 should be empty, but 5th is the front desk 7th disk, all the documents in the inside. So I changed the slots for HDISK8 and 6, and I was going to try to restart,

Nice, start success!

Because the parameter used when cloning the system is-co so, after entering the system, you need to reconfigure some parameters,

Smitty MKTCPIP Modify IP Address

hostname=* Modifying host Names

Complete.

See the front of the host has yellow lights, diag inside off the lights, errclear clear the log, observe a few days will still be error.

The above fault is p630 a hard drive is broken, and then I unmirror when all kinds of failure, and finally directly on the new disk, three pieces together to do a mirror, restart, direct 0557 hint, forced to have no way to clone. I hope we can help you.
