I've got an NDMP client (Celerra) with two file systems - /vol0, and /vol1.
When I run the backup (fulls only), /vol1 gets a complete backup, but /vol0
backs up only a few kilobytes, and the process ends as Successful.
To be more specific:
06/12/08 10:17:12 ANR2017I Administrator RNLEAF issued command: BACKUP
NODE
SVGMN14GLBSM07 /vol0 mode=full (SESSION: 36846)
06/12/08 10:17:14 ANR1063I Full backup of NAS node SVGMN14GLBSM07, file
system /vol0, started as process 552 by
administrator
RNLEAF. (SESSION: 36846, PROCESS: 552)
...
06/12/08 10:17:37 ANR0988I Process 552 for BACKUP NAS (FULL) running in
the
BACKGROUND processed 43,482 bytes with a completion
state
of SUCCESS at 10:17:37. (SESSION: 36846, PROCESS:

and...
06/12/08 10:17:14 ANR2017I Administrator RNLEAF issued command: BACKUP
NODE
SVGMN14GLBSM07 /vol1 mode=full (SESSION: 36846,
PROCESS:
552)
06/12/08 10:17:16 ANR1063I Full backup of NAS node SVGMN14GLBSM07, file
system /vol1, started as process 553 by
administrator
RNLEAF. (SESSION: 36846, PROCESS: 553)
...
06/12/08 15:26:39 ANR0988I Process 553 for BACKUP NAS (FULL) running in
the
BACKGROUND processed 620,126,384,679 bytes with a
completion state of SUCCESS at 15:26:39. (SESSION:
36846,
PROCESS: 553)
Now, the administrator of the Celerra can demonstrate that /vol0 has plenty
of data in it:
[nasadmin@us_bank_cs702_5948 nasadmin]$ nas_fs -size vol0
total = 1578910 avail = 900497 used = 678412 ( 42% ) (sizes in MB)
( blockcount = 3283714048 )
volume: total = 1603376 (sizes in MB) ( blockcount = 3283714048 ))
[nasadmin@us_bank_cs702_5948 nasadmin]$ nas_fs -size vol1
total = 1578910 avail = 985584 used = 593326 ( 37% ) (sizes in MB)
( blockcount = 3283714048 )
volume: total = 1603376 (sizes in MB) ( blockcount = 3283714048 ))
I see something similar when I look at the information TSM has about that
file space:
q filespace SVGMN14GLBSM07 /vol0 f=d
Node Name: SVGMN14GLBSM07
Filespace Name: /vol0
Hexadecimal Filespace Name:
FSID: 2
Platform: DartOS
Filespace Type: uxfs
Is Filespace Unicode?: No
Capacity (MB): 1,578,910.2
Pct Util: 43.0
Last Backup Start Date/Time: 06/12/08 10:17:13
Days Since Last Backup Started: <1
Last Backup Completion Date/Time: 06/12/08 10:17:36
Days Since Last Backup Completed: <1
Last Full NAS Image Backup Completion Date/Time: 06/12/08 10:17:36
Days Since Last Full NAS Image Backup Completed: <1
I don't know what kind of settings he might have on his end that might
affect how TSM accesses, or fails to access, a file system on the Celerra.
As you can see, the commands issued to invoke the backups are identical. No
client option sets are applied to the node.
TSM server is ver 5.3.5.2 on AIX 5.3; backing up to a VTL emulating a 3584
with LTO drives. If the version of DART on the Celerra matters, I'll dig it
up.
Does anyone have a theory as to why the /vol0 backup isn't backing up the
data that's there, while the backups of /vol1 are working fine?,
Thanks in advance!
