EF & E-Series, SANtricity, and Related Plug-ins
We have a few E2600s that are now out of support. One of them seemed to have a controller failure recently, and somehow it got fully messed up in that the other controller got locked up, and the unit became unusable. Eventually we got the controller unlocked, but now that controller lost all the configuration and reports the unit as if it had never been configured. Wondering if there's a way to recover the configuration from the disks, before I completely give up and wipe away all the data. We could even move all the disks to a similar unit and try recovering there. But all my attempts have failed so far... Thanks for any pointers...
Jorge
Hi jorge,
The configuration information is stored in the DACstore which live in each drive depending on your firmware version
How did you unlock the controller ?
How do you see you lost all configuration ? Santricity ?
"reports the unit as if it had never been configured" --> what message do you have exactly (error or warning or information) ?
Do you have an old support bundle ?
After a long time looking around, I unlocked the controller by going in through the serial console and doing lemClearLockdown. Before doing that, I couldn't really do anything else.
When I see the unit now in Santricity, it gives me the default configuration screen, asking if I want to create a disk pool and saying I have 60 disks available. I also am able to connect using SMcli, and do a show storageArray healthStatus; which returns the following:
show storageArray healthStatus
;
The controller clocks in the storage array are out of synchronization with the storage management station.

I'm worried about the fact that it says that the database on the drives is invalid...
Okayyyyy
When controllers detect corruption in the primary database, they reboot and enter a Lockdown state, which is the Recovery Mode.
Just to confirm. What does the seven segment display shows you ?
1- You should have on the santricity host the backup configuration file. In Windows, this is under C:\Program Files (x86)\StorageManager\client\data\monitor\dbcapture.
2- Go on the enterprise management window > right-click > Execute script and type the following command
(Check the help about this command by going in the menu Help > commande reference)
load storageArray dbmDatabase file=”<configuration file name>"
3- Check the syntax and Execute the command
Controler should exit the recovery mode afterwards, if not clear it.
Hmmm. What is "the seven segment display"?
Our Santricity is running on linux, not Windows, and it is managing several hosts. Not sure how we could find the backup configuration file there...
The seven segment display is a small LED screen on the back of the controller.
Try in /opt or /bin
Hi,
Please refer Kb 3014685 What procedure needs to be followed if a controller enters lockdown?
Hello Jorge,
Did you find any backup file ?
If not, I have an alternative but I would need a recent support bundle. I can try to generate a recovery script
or
You can clear the recovery mode but with no garanty that the controller will like it.
Hello again,
Sorry about the no reply yesterday, other crisis took precedence. Anyway, here are the answers to your questions:
The seven segment display is showing 00 for the non-faulty controller, and 0E, then Lt for the faulty controller.
I didn't find a backup file, but I'm not sure what I'm looking for. Any particular name for the file I'm looking for? Hmmm. Maybe I did find something. I looked for anything called .cfg, and there's this candidate:
./opt/SM/FirmwareUpgradeReports/genome-cloudstore/genome-cloudstore_60080E500023B966000000004F8805F3_Configuration.cfg
I found a couple of old support bundles, but they are for a different array. We have other arrays with similar configurations, if that would help.
Welcome back.
Haha no worries.
1- 0E + Lt means that he is in recovery mode.
2- I know that in windows it lives in a zip file
3- No, you can't take support bundle from other array, there is some specific values volume wwn or capacity or assigned drives that would not match.
Let's try something else then. Type the following command on both controllers and send me the output please
bdbmShowBackupDatabaseInfo
Hi again,
I tried running the command "bdbmShowBackupDatabaseInfo" on the controllers. Could only run it on one controller, and the output was:

This is not a good sign :

the both places were are stored config backup are unreadable :S
little correction on my statement 2 replies before, Lt is a lockdown code for database corrupted
Is this the configuration file you want? This is from when we recently upgraded the firmware on the unit:

ohhh yeah it looks like it but instead of create we should do a recover.
What I would do is to :
- See if from that file I can generate a recovery script
- Wipe the data (normally the data should not be deleted) by setting an option in the VKI_EDIT_OPTIONS
- Once the controllers are up and running clear the options in the VKI_EDIT_OPTIONS
- Execute the recovery script
Since I forgot my charger at work I'm out of battery - Will contact you back on Monday to continue working with you on it and check if it's doable
That sounds wonderful! Thanks so much for all the help!!!!
By the way, it seems that, under linux, there's a treasure trove of data under /var/opt/SM - that's where I found this information, as well as a lot of other files for the other untis we have...
hello jorge,
do you have a dbm backup in the following path
/var/opt/SM/monitor/dbcapture/
Many thanks
Hello Jorge,
May be you have found some support bundle.
Let me know.
Thanks
There are a lot of files in the /var/opt/SM/monitor/dbcapture directory. I think the appropriate ones are:
-rw-rw-r-- 1 root root 744547 Mar 7 09:11 RetrievedRecords_60080e500023b966000000004f8805f3_2016_03_07_09_11_33.dbm.zip

Is this what you're looking for? What do I do with them?
So, I'm wondering if, from your earlier post, what I need to do is to pick one of the files on the dbcapture directory (I assume the latest file) and do a:
load storageArray dbmDatabase file=”RetrievedRecords_60080e500023b966000000004f8805f3_2016_03_07_17_29_17.dbm.zip"
(maybe I need to unzip it first)... Is that all, or do I need to do something before that? You mentioned something about generating a recovery script, but not sure how to do that... Thanks!
hello jorge,
Hope you are doing well.
If you have the DBM, that perfect.
I would the DBM zip file and the 2 serial numbers of controller A et Controller B to generate a validator key to be able to recover the system (Send it by PM)
Many thanks
