Error description

  • During the "Backup Stgpool" process, a hardware or media error
can be encountered which is not severe enough to stop the
process from running, but does not correctly report any files or
 bytes which were skipped and unread during the process.

Tivoli Storage Manager Versions Affected:
All supported versions and all supported operating systems

Customer/L2 Diagnostics (If Applicable)

An example of this :

ANR1210I Backup of primary storage pool PRITAPE to copy storage
pool COPYTAPE started as process 904.
ANR1228I Removable volume 123456L5 is required for storage pool
backup. (SESSION: 190674, PROCESS: 904)

During the Backup Stgpool process, a hardware/media error is
encountered :

ANR8944E Hardware or media error on drive DRIVE1 (/dev/rmt1)
with volume 123456L5 (OP=READ, Error Number= 110, CC=0, KEY=03,
ASC=11, ASCQ=00,
SENSE=F0.00.03.00.04.00.00.58.00.00.00.00.11.00.36.00.70-

ANR8359E Media fault detected on LTO volume 123456L5 in drive
DRIVE1 (/dev/rmt1) of library MYLIB1.
                          (SESSION: 190674, PROCESS: 904)
. . .

The process continues and ends successfully :


ANR0986I Process 904 for BACKUP STORAGE POOL running in the
FOREGROUND processed 281 items for a total of
                          3,827,887,299,096 bytes with a
completion  state of SUCCESS at 15:49:28. (SESSION: 190674,
PROCESS: 904)
ANR1214I Backup of primary storage pool     PRITAPE to copy
storage pool COPYTAPE has ended.  Files Backed Up:
281, Bytes Backed Up: 3827887299096, Unreadable Files: 0,
Unreadable Bytes: 0. (SESSION: 190674)

Notice that 0 unreadable files/bytes are reported.

Issuing a Q CONT against this volume shows, shows that a file
was not copied successfully  :

q content 123456L5 copied=no

Node Name  Type   Filespace   FSID  Client's Name
---------  ----   ----------  ----  --------------
MYNODE     Bkup   /dev/PROD   6548  TSMData/MYFILE


So a single file is not copied on this volume, because of the
hardware/media error seen. A trace of this with server classes
as, af, ss will show :

16:12:06.579 [406958][asalloc.c][4891][AsWriteSeg]:Writing

The key return code to look for is the "rc=3016"
(GRC_INPUT_ERROR_SKIP) which actually skips the file during the
process, but does not record this as being unread.

Local fix

  • Ensure the "Backup Stgpool" is performed to a drive which is not
 showing any hardware errors, or review if this is a true media
error and either audit or restore the volume appropriately.
