Ignite recovery for a DR system

[Fidel Ramirez_1]

Hello,

We have two different subnets, Production and Disaster Recovery. Each one has their own Ignite server.

The DR ignite server was originally configured when it was connected to the production subnet. Its clients at that time were the production systems and an Ignite network archive was created for each.

Then, the DR Ignite server was moved to the DR subnet and I started recovering from the original (production) clients to the DR clients.

After making a few changes, a couple systems were recovered from production to DR but two others are failing.

On one recover the failing is because of HP-Auto Port Aggregation and on the other because the DR system is HP-UX 11.11 but the archive is from HP-UX 11.31.

Despite being successful on two Ignite recovery archives from Production to DR, apparently the preferred way for doing this is a Golden Image.

I would like to know if this is true and, if so, what would be the steps for doing this kind of recovery.

Thank you,

Fidel

Shalom,

These recoveries should either work or not.

We really don't know enough to solve this issue.

A 11.31 image taken from an IA-64(Otherwise known as Itanium) can not be recovered to an 11.11 system which is PA-RISC.

I don't see why APA should stop the system recovery, the system should still build and simply not have networking. You would need post install to disable APA and configure the system to work without APA.

Golden image is not going to have any impact on the scenarios above.

Please post the following info on the failed recoveries source and destination systems:

Hi Steve,

Here are more details.

Case where Ignire recovery is complaining with HP-AutoPort Aggregation

Source machine:

# model
ia64 hp server BL860c

# lanscan
Hardware Station        Crd Hdw   Net-Interface  NM  MAC       HP-DLPI DLPI

LinkAgg4 0x000000000000 904 DOWN  lan904 snap904 10  ETHER     Yes     119

Target: System is down and not booting

Model is rx2660

lanscan: From Ignite View Hardware:

LAN Interfaces:

Interface Name     LAN Address              Description                         H/W Path

/dev/lan0               001B789F4151          HP_PCI-X_1000Base-T      0/1/2/0

 /dev/lan1              001B789F4150          HP_PCI-X_1000Base-T      0/1/2/1

On the other case, the source system is HP-UX 11.31 and  target is HP-UX 11.11

Source:

# model
9000/800/rp3440 

Target: 9000/800/rp4440

In this case, I'm thinking installing first HP-UX 11.31 on the target and then re doing the Ignite recover to make both systems, Production and DR, identical.

I'm attaching a screen capture of the recovery error.

Thank you for your prompt answer,

Fidel

Hi,
as the log shows, you need to specify the '-R' option when booting the 11.11 client from the ignite-ux server, because you booted by default 11.11 kernel and you want to install 11.31 OS.

so add to the command line '-R B.11.31'

[g3jza]

Or when booting not by using 'bootsys' from the client (but from the BCH/console, ) , then select 11.31 kernel as well

[Fidel Ramirez_1]

Hi g3jza,

Thank you for your reply.

I ran the command:

/opt/ignite/bootsys -wv -S -R B.11.31 usporx91 2>/var/tmp/daa022625

but it is giving the same error.

In the meantime, I will install 11.31 from DVD on the target and try again the Recovery to see if it works.

Fidel

[g3jza]

What if you try booting directly from the console/BCH and selecting the 11.31 Kernel directly?

[Fidel Ramirez_1]

What I did was install HP-UX 11.31 and then the recovery.

It worked but I'm seen missing directories on /var and /opt.

I haven't assigned points to people and I want to do it.

How does it work now?

Hi:

Click on the 'Kudo's icon next to the person or persons to whom you want to give the "point".
