The operation was terminated on the NDMP server - Snapsure configuration

Hi DynaMox. Thanks for your fast reply.

I followed your advice: We set the NDMP snapsure config as following.

(Did not restart the NAS or anything else)

[root@nas]#server_param server_2 -facility NDMP -modify snapsure -value 0

RESULT:

[root@nas]# server_param server_2 -f NDMP -i snapsure -v
server_2 :
name                    = snapsure
facility_name           = NDMP
default_value           = 0
current_value           = 0
configured_value        = 0
user_action             = none
change_effective        = immediate
range                   = (0,1)
description             = Use SnapSure file system for backup

Then from Symantec Backup Exec backup server we restarted the job. After 10  minutes or so we got the same error again (The operation was terminated on the NDMP server etc..)

ALSO SEE LAST LINES FROM LOG FROM COMMAND server_log server_2: (IMPORTANTE: WHEN THE VALUE WAS ON 1, THE JOB ABORTED IMMEDIATELY, NOW IT ABORTS AFTER 10 MINUTES OR SO

Please help.

Thanks.

i actually don't think you need to enable that parameter for Backup exec as it passes that parameter when it talks to the datamover. Some application can't pass that parameter (TSM for example) so you have to set that parameter manually.  Try setting that parameter back to 0 and give it a try again. If it still fails, please provide a log entries from the datamover itself around the time you tried to run your backup job. To view log on datamover use the following command on control station:

server_log server_2

Ok,

i ran the command to check the license

[root@nasserver]# nas_license -list

key                 status    value
site_key            online    4a 66 f4 92
advancedmanager     online
cifs                online
nfs                 online
iscsi               online
snapsure            online

i don't think this is the issue but let's verify snapsure is licensed:

nas_license -list

Hmm..i wonder if there is not enough space in the pool where that file system resides. Let's create a snapsure checkpoint manually and see if it succeeds.

fs_ckpt -name testcheckpoint -Create

if it succeeds , delete it

nas_fs -delete testcheckpoint -o umount=yes

do you have tape drives presented to datamovers ?

oops. i think that i did not provide sufficient info. it is not a problem with pool space ...

We use Symantec Backup exec with ndmp to backup network resources and folders that are located ON THE NAS CELERRA  TO OUR QUANTUM SCALAR 50.

We can do a backup sucessfully directly to the QUANTUM SCALAR 50 from our backup server (with Symantec Backup exec) from files and folders that are located on the network. Quantum scalar 50 works ok. The tapes are being used correctly.

But if we want backup resources (what to backup and where) located on the NAS, it fails: see screenshots (in Spanish, sorry):

SEGCIFS = IS OUR CELERRA NAS

Hi,

present tape drives to data movers-  ?

Is there is easy command to see that information?

i ran this command:

[root@csgesitur nasadmin]# nas_server -info server_2
id        = 1
name      = server_2
acl       = 0
type      = nas
slot      = 2
member_of =
standby   = server_3, policy=auto
status    :
  defined = enabled

Hi again

i can confirm you that the tapes in the Quantum cabinet are correctly presented to the datamovers.

We do not know if we also must present those tapes to the datamover on the Celerra NAS side. ??

please help

NDMP backups can be accomplished via IP , where your backup servers pulls data from the datamover over your ip network or you can present a couple of tape drives directly to datamovers (via AUX ports on datamover) and perform backups via fiber channel network. Which option are you trying to do ?

in backup exec, can you "uncheck" snapshots so it does not try to create one.

Hi,

We do backup (NDMP backups) via IP

We have the backup server  which pulls the data from the NAS

see screenshot

Then destination to Quantum

Quantum device info:

please help

Hi,

If we uncheck the snapshots option, then we lose the option off having SnapSure snapshots.  We obtained a license for that

[root@csgesitur nasadmin]# server_param server_2 -facility NDMP -list
server_2 :
param_name                       facility  default     current   configured
maxProtocolVersion                  NDMP          4          4

Also, Symantec reported: (and they refer to EMC)

Problem

try these commands and tell me if they complete ok

fs_ckpt -name testcheckpoint -Create

if it succeeds , delete it

nas_fs -delete testcheckpoint -o umount=yes

Hi,

Yes !!! know we found out why it not work. you were right !!! no space in pool

we ran

fs_ckpt id=xx -name testcheckpoint -Create  (id obtained via nas_fs -list command)

and we got:

operation in progress (not interruptible)...Error 12013: A pool could not be found on the storage system(s) CKM00085200043 to satisfy the request.

we cleaned some space in the pool via Celerra Gui console

re-ran the fs_ckpt command and finished ok. checkpoint created. Now we re-ran the backup job  and finished ok.

Thank you !!!! 

Gracias
