FMM0772W AND FMM1241E LINUX RESTORE FAILURE IF VOLUME GROUPS CONTAIN INACTIVE LOGICAL VOLUMES
|
| product: |
FLSHCPY DB2 AGE / 5608AC6DB / 41L - DB2 |
| Problem description: |
IBM Spectrum Protect Snapshot restore operations on Linux may
fail with warning message FMM0772W and the error message
FMM1241E indicating that some file systems that should be
restored could not be unmounted. IBM Spectrum Protect Snapshot
erroneously detects that a volume group does not contain any
file system. But in fact the volume group contains multiple
logical volumes which some are in state available and file
systems are mounted and others are in state NOT available and
don't have file systems mounted. This causes IBM Spectrum
Protect Snapshot to leave those mentioned file systems mounted
during the restore operation which subsequently causes the error
message FMM1241E.
L2 Diagnostic:
The restore log file shows the warning message FMM0772W and the
error message FMM1241E:

| Problem Summary: |
****************************************************************
* USERS AFFECTED: *
* Users of IBM Tivoli Storage FlashCopy Manager v3.1.0 trough *
* v4.1.6 for Linux on all applications. *
****************************************************************
* PROBLEM DESCRIPTION: *
* During the restore operation, IBM Tivoli Storage *
* FlashCopy(R) Manager for Linux can end with error message *
* FMM1241E when the production *
* logical volumes on the Linux host are inactive. *
****************************************************************
* RECOMMENDATION: *
* Verify the status of the logical volume using the Logical *
* Volume Manage commands: *
* Example of inactive logical volume: *
* The Linux LVM command "lvdisplay" will show the inactive *
* status of the corresponding logical volumes. *
* Below is an example output of the lvdisplay command: *
* --- Logical volume --- *
* LV Path /dev/ut80tmpvg/lvdata_evm1n0_new *
* LV Name lvdata_evm1n0_new *

The restore log file shows the warning message FMM0772W and the
error message FMM1241E:
FMM0772W The database volume groups do not contain currently any
file system.
FMM1241E Unable to unmount the following filesystems:
Below is an example of a list of file systems:
/opt/db2opensys/db/pcinst/NODE0000
/usr/dbtmp/pcinst/db2csa/p0 |
| Local Fix: |
Identify the reason why the volume group contains a logical
volume that is in status 'NOT available'.
Remove this logical volume or activate it and create a file
system on it and rerun the snapshot restore operation. |
