1. Executing command kill -12 on the cellsrv pid.

Identify the pid of cellsrv process -> ps -ef |grep ‘cellsrv 100′
kill -12
Example:

# ps -ef |grep 'cellsrv 100'
root 15182 30943 0 16:34 pts/0 00:00:00 grep cellsrv 100
root 25280 25278 0 Aug08 ? 00:18:38 /opt/oracle/cell11.2.2.2.0_LINUX.X64_101206.2/cellsrv/bin/cellsrv 100 5000 9 5042

#kill -12 25280

2. On the storage cell, obtain the statedump by running command from cellcli:

cellcli>alter cell events = "immediate cellsrv.cellsrv_statedump(0,0)"

3. Provide to the Service Request the trace file generated on the storage cell, located under:

#cd $ADR_BASE/diag/asm/cell/<hostname>/trace

The statedump is generated on the thread 0 of cellsrv. The file will have name like svtrc_ _0.trc.
Collect all the the files svtrc_ _X.trc, together with ms-odl* and alert.log
