Date - 09/2007
Affected Product & Version - NetVault: Backup 7.4.5
Affected Module & Version - NDMP plugin v6.304
OS Version - Windows 2000/2003
Application Information - EMC Celerra DART OS 5.5
Description:
NDMP backup fails with error - "Invalid backup path".
Symptoms:
NetVault receives internal NDMP server error when either when incorrect PATH name was specified in NDMP plugin or the target file system isn't mounted -
NDMP: ERROR 0: The process id for NDMP service is 0x83691200 Invalid backup path
Data operation halted due to unrecoverable internal NDMP server error
Make sure that the desired backup target is mounted by running "server_mount ". If the file system isn't mounted, run "server_mount -all" and check the list of mounted file system again. Here is an example of the output from the "server_mount " command -
$ server_mount server_2
server_2:
root_fs_1 on / uxfs,perm,rw
root_fs_common on /.etc_common uxfs,perm,ro
ufs1 on /ufs1 uxfs,perm,rw
"/ufs1" is the file system mount point that would be entered in NDMP plugin configuration to backup that particular data.
If the file system is associated with VDM on the Data Mover, the command would show something like -
server_2 :
root_fs_vdm_Marketing on /root_vdm_1/.etc uxfs,perm,rw
Mkt_Shared on /root_vdm_1/Mkt_Shared uxfs,perm,rw
Mkt_User on /root_vdm_1/Mkt_User uxfs,perm,rw
"/root_vdm_1/Mkt_User" in this example indicates that the file system is a VDM-configured file system. The full path "/root_vdm_1/Mkt_User" has to be put in NDMP plugin configuration.
Note that, if the file system to be backed up is shared by CIFS, the file system has to be exported first prior to mounting the file system. Verify that the CIFS shares are created/exported by "server_export ". For example,
$ server_export Marketing
Marketing :
share “Shared_Files” “/Mkt_user” maxusr=4294967295 umask=22
Making sure that exported file system in VDM is mounted, double check that cifs service is mapped by "nas_server -info -vdm " -
$ nas_server -info -vdm Marketing
id = 1
name = Marketing
acl = 0
type = vdm
server = server_2
rootfs = root_fs_vdm_Marketing
I18N mode = UNICODE
mountedfs = Mkt_user
member_of =
standby =
status :
defined = enabled
actual = loaded, active
Interfaces to services mapping:
Interface = Mkt:cifs
