1. What does this mean to me?
It takes 2 to 4 hours for a complete software install on the
iR110/125/150's hard disks
With procedures outlined in this page, it is possible to create, store
and have ready an exact replica (clone) of a iR110/125/150's hard disk
In the event of a hard disk related hardware or software failure an
iR110 customer can be up and running within minutes.
3. What hardware do I need to have ready?
This procedure assumes the source drive and clone drive are identical.
You may have to purchase two brand new hard disks.
The current specifications for the Ultra 10 include 3 types of 20 Gig EIDE hard disks
Seagate ST320420A
(20.4GB - 7200 RPM Ultra ATA/66)
Barracuda ATA II
Seagate ST320414A
(20.0GB - 7200 RPM Ultra ATA/100)
Barracuda ATA III
Seagate ST320011A
(20.0GB - 7200 RPM Ultra ATA/100)
Barracuda ATA IV
These drives must be purchased directly from Sun for they have special firmware to allow the Ultra 10 to "See" the entire 20 GB
This is a direct quote from www.sun.com
"The new 20-GB EIDE drives from Sun have firmware in place that allow Solaris 2.5.1 and Solaris 2.6 users to access the entire disk. This may not be true of 3rd party EIDE drives."
We purchased 2 Seagate ST320011A's and tried. It is true. The Ultra 10 will see only 8GB.
According to Sun, these hard disks are about $300.00 US
The Hard Disk Cloning procedure then represents 0.33% of the cost of a loaded iR110
It is silly to not consider 2 identical drives to provide a total
customer solution.
4. I am ready to Clone my iR110 Ultra
10. I need a step by step procedure
Step by Step 1. Before doing anything
2. Get your two new hard disks out of their packaging and take note of the jumper settings. 4. Installing the iR110 software
Command #1 completes in less than 1 second
Command #2 will take about 30 minutes Please be
patient 11. Type init 0 to reboot the machine to the OK prompt
|
It would be wise to check the Cloned disk
Disconnect the Cloned disk from the Slave connector and put it on the
Master connector
Connect the Ultra 10 power connector and boot it up
Hopefully it will boot properly
Let it boot all the way to the OCI login
Test the clone out to make sure everything is cool.
Use init 5 to shut it down properly
If it does not boot properly, try repeating the cloning process again
6. Disconnecting the Cloned disk
It would be wise to now disconnect the cloned disk and leave it in the
machine in case of an emergency
After that we should tell the Ultra 10 that a new hardware change has
occured
1. Disconnect the power cable.Congrats. You are finally done.
2. Disconnect the 'slave' drive power connector and the IDE connector.
3. Reconnect the 'master' drive power connector and the IDE connector
3. Reconnect the power supply cable and reboot the Ultra 10
4. Wait until the Ultra 10 completely reboots
5. Use su - to root
6. Type init 0 (This will shutdown to the OK prompt)
7. Type boot -r (This will reboot the machine and look for hardware changes)
7. In an emergency how should I use the
cloned disk?
You could be in one of two situations:
1. You have 2 disks in the Ultra 10 and you already followed
the procedure in this page
2. Your customer only has 1 hard disk and you have not yet
cloned. (For situation 2, check out step 10 below)
I am assuming you have 2 disks and have followed the procedures in this page to create a cloned image
If the customers original hard disk is still operational, you may be
able to still access any of their files on the hard disk (Optional)
If however it is totally dead skip the (Optional) step below.
Your Ultra 10 should boot successfullyYou will have to use touch reconfigure or boot -r to get the Ultra 10 to "See" the hardware changes. See Item 10 1. Power off the Ultra 10 and disconnect the power cable
2. Remove the Ultra 10 cover as outlined above
3. Disconnect the Master and Slave drive connections
4. Put the Slave drive (The clone) onto the Master drive connector
5. Optional. Put the Master drive (The problematic original) onto the Slave connector
6. Reconnect the power cable and power up the Ultra 10
8. Can I use a clone of one Ultra 10 on a
different Ultra 10?
I tried this in our lab on one machine and Yes it appears to work
When the Ultra 10 boots, it will find probably find a SCS key mismatch
This is the error I got
Not Licenced for any known product configurationsEnter the correct SCS licence key and you should be up and runningObtain the SCS licence key for the host ID: XXXXXXX
Enter licence key (or press return to continue)
9. What does Slice and c0t0d0s0 mean
In Unix world, a partition is called a slice.
The root slice is 0, slice 1 is swap
Slice 2 is the entire disk!!
Here is an explanation of the c0t0d0s0 thing
So...
c0t0d0s2 Is Slice 2 of the master hard disk
c0t1d0s2 Is Slice 2 of the slave hard disk
10. I need to tell the Ultra 10 to look
for new hardware changes
If you plan to add new hardware to the Ultra 10, you must tell the
machine to look for the new hardware
There are two methods:
1. Touch Reconfigure (This will
cause the Ultra 10 to look for new hardware changes on the nextboot)
2. Type boot -r (This will boot the Ultra 10 now
and new hardware changes will be scanned)
Touch Reconfigure
1. Start a Command tool
2. Use su - to logon as root
3. Type touch reconfigure.
boot -r (From the ok prompt only)
1. Use init 0 to get to the ok prompt
2. You can also use stop a but this is very
dangerous and not recommended
3. Type boot -r
11. How can I wipe my Ultra 10 hard disk
clean and start fresh?
1. Use su - to root
2. Type init 0 (shutdown to run level 0, OK
prompt)
3. Insert the iR110 Operating System Software CD into the
CD-ROM
4. Type boot cdrom -s
5. Wait for the machine to boot (About 4 minutes)
6. Type format and hit enter
7. Select the disk you want to format
8. Select p and hit enter
9. Select p and hit enter (again)
10. This will print to the screen the current slice table
Here is an example of our Ultra 10 with a Seagate ST320420A

11. You will be repeating the following steps for all partitions exept partition 2. Do not delete partition 2.
Select the partition you want to delete by typing the partition number and hitting enterAfter you are done, select p and then enter to print the current slice table to the screen.
Enter Partition ID tag: Enter

12. Type label enter. Then confirm with y (This will write the slice table to the hard disk)
The Ultra 10 hard disk is now ready for a fresh install.
Type init 0 and begin the installation procedure
