Failed Controllstation installation

Re-installation is a service task - please contact your service provider

are there any documents,or procedure to fix that problem.?

DME fault led status always on.may the problem appears because of thıs.?

If the control volume is

Thin : Unmap the device, unbind the device, rebind the device then map the device to the front end port as LUN 0.

Thick : Unmap the device and map the device to the front end port as LUN 0.

If the Control luns are not zeroed before the File OE re-install it will also fail at the step below:

A valid partition exists on LUN 0. Performing a fresh install would result in loss of system data. If you are sure you want to perform a fresh install, you must zero out LUN 0 and try again. Exiting install...

Type 'C' to continue: Type 'C' to continue:

To fix this:

1. Press C and the CS will take you to the login prompt.

2. login as root

3. Execute the command below to zero all the control LUNS 0,4 and 5.

dd if=/dev/zero of=/dev/nda bs=1M count=100

dd if=/dev/zero of=/dev/nde bs=1MB count=2000

dd if=/dev/zero of=/dev/ndf bs=1MB count=63k

Please note this may take some time for the third command to complete as the /dev/ndf size is 134217344 KB

After this is done continue with the FILE OE re-install.

Thanks this worked.

Execute below commands:

dd if=/dev/zero of=/dev/nda bs=1M count=100

dd if=/dev/zero of=/dev/nde bs=1MB count=2000

dd if=/dev/zero of=/dev/ndf bs=1MB count=63k

After running these command make sure you reboot the control station & restart the File OE installation

P.S> do not directly ersume the File OE script post executing the commands, reboot is required.

Hi!

Sorry for necroposting.

I'm trying to reinstall my CS as well.

So I zero out these 3 LUNs, and after reboot installation ends with error:

Initializing server in slot 2 as server_2 ...

Press to exit:

This is different issue than zeroing the control luns.

Control Luns appears trespassed and also appears not seeing the disks. Raising a support ticket is the easiest way here.

Anyway, if you get the prompt, check the DM is booted ( /nasmcd/getreason) , check the HBA status ( /nasmcd/sbin/t2tty -c 2 "fcp show", Disks (/nasmcd/sbin/t2tty -c 2 "camshowconfig") - If no /nasmcd directory, /tftpboot also will have the commands.

We out of support on this VNX, so I'm on my own here

One of Control LUNs is trespassed, and I can't trespass it back nor in GUI nor in navicli - it says no such LUN

NaviSECCli.exe -user sysadmin -password sysadmin -scope 0 -h 10.209.101.3 trespass lun 4095

Error: trespass command failed

LUN does not exist

So here is a output:

# /nasmcd/getreason

6 - slot_0 control station ready

4 - slot_2 configured

4 - slot_3 configured

# /nasmcd/sbin/t2tty -c 2 "fcp show"

Is there a manual to reinstall CS correctly, and take in account all pre requirements, and to troubleshoot known cases?

/nasmcd/sbin/t2tty -c 2 "camtrespass c0t0l0"

That above command will trespass the lun back to spa on chain 0.

I dont think you will find a manual for this kind of CE's activities. Even Knowledge articles also most likely visible to CEs only.

Thanks! Now I try to reinstall it once again.

Everything went well!

Trespassed lun was the problem!
