The major config like file systems, shares, ... isn’t kept on the control station HDD so it will be recovered and the system config will look like the old.
There might be some details like control station IP or callhome config that need to be recovered or entered manually during the procedure.
Also any changes that you have done manually to local files or content in /home/nasadmin will be lost unless you can find a backup.
If you need the exact procedure than you need to ask the support engineer doing or helping with the replacement for it.
Sorry Maynor did not get to your reply sooner. All of what was stated by Dynamox and Ranier is correct. It will just be any site specific stuff that you had in the /home directory that will have to be restored if the Control Station is dead.Everything else should be as it was before the replacement.As stated your local
EMC rep will help with any and all the details.
Since the Control station OS is on the local hard drive and not on the backend storage,all the data and configuration information on Control station must be recovered from backup.
the NASDB backup process backups EMC NAS information to the backend on hourly basis
After replacing control station the following items may be recoverable Via NASDB backup:
2)selected files from control station's /etc
as mentioned by Rainer earlier
replacement of a control station is done by an EMC or service partner technician and they will have the necessary infomation and procedure .
let us know if this helps
Maynor need not to be worried about any backup and restore of configuration for the control station. What ever needs to be done will be done by the EMC engineer following standard procedure to replace a control station. The NAS related configuration and the NASDB backup are on the shared storage and can reconfigure the replacement control station.
However, during the replacement of the control station - following information is needed with respect to control station. EMC engineer may ask for these - so please keep them available
1) Host name
2) IP Address
5) Domain Name
6) DNS servers
The Time zone, Time and NTP server need to be set up manually.
However, in this process, if any files/folders were stored manually on the faulted control station (although you should not keep anything on the control station manually).
thanks to all
litle by litle, i am feeding and undertanding the way a CS replacement can be done.
great and valuable information.
great for "shared storage"
i will be ready for all information required before doing this job
1. what could hapend if i need to do an emergency NAS shutdown, does the datamovers going to start normally giving their CIFS, NFS, etc,
service available without a CS?
2. still NASDB backup command, is executing without CS on each datamovers?
3. is a good practice to backup local CS hard disk? why?
in my case if a file system was corrupted and unrecoverable, how could i be use a recently backup of the local CS hard disk,
if there is no access to linux OS
4. can i think in using some backup bearmetal image hard disk product, could that help.
5. any tip or command to try recover the filesystem meanwhile new CS arrived, i already had a serial conection to the control station.
(sorry for my english) and spend all my point to asign
you don't need a backup of the control station HDD but you might want to copy the already done nasdb backup and any local content to another system or backup
I contains everything support would need to re-create the config
I don't think we allow bare-metal recover to interfere with our replacement procedure
Rainerno, without a control station you can't boot the system
