DB2 - Problem description
| Problem IT06424 | Status: Closed |
ENHANCED-CAPABLE(EC) VG'S CAN REMAIN VARIED-ON IN READ-WRITE MODE ON THE STANDBY NODE. | |
| product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
| Problem description: | |
During failover, DB2 leaves non-concurrent Enhanced-Capable(EC)
volume groups(VGs) in varied-on mode on the standby node. As a
result, this introduces the possibility of unexpected changes to
the DB2 files on the affected file systems. This APAR addresses
this issue by allowing non-concurrent EC VGs to be varied off
during a DB2 failover.
This is achieved by removing the following check from the
mountV97_stop.ksh script:
'$concurrent != "Enhanced-Capable" &&'
This check is being made in two places:
1)
################################################################
# Start main...
rc=0
if [[ "${rlv}" == "true" && $concurrent != "Enhanced-Capable" &&
"X$vfs" != "Xmmfs" && -z $isVgManaged ]]; then
# RLV
logger -i -p notice -t $myname "$vgname is RLV"
varyoffvg ${vgname?}
...
2)
# Filesystem is unmounted or was not mounted
if [[ "${UNAME}" == "AIX" && $concurrent != "Enhanced-Capable"
&& "X$vfs" != "Xmmfs" && -z $isVgManaged ]]; then
varyoffvg ${vgname?}
lspvLine=$(lspv -L | grep " $vgname ")
vgactive=$(echo $lspvLine | awk '{print $4}')
