Create Business Copy
We are trying to create business copy.
After paircreate, we created horcm6.conf.
We are getting this message in pairdisplay:
dbgrp6 matrixih03(L) (CL1-J , 0, 2-0)31266 449..P-VOL PAIR,31266 467 -
dbgrp6 matrixih03(R) (CL1-E , 4, 2-0)31266 ----..---- ----,----- ---- -
dbgrp6 matrixih04(L) (CL1-J , 0, 3-0)31266 450..P-VOL PAIR,31266 468 -
dbgrp6 matrixih04(R) (CL1-E , 4, 3-0)31266 354..SMPL ----,----- ---- -
when in fact we should be getting something like:
dbgrp6 matrixih06(L) (CL1-J , 0, 5-0)31266 452..P-VOL PSUS,31266 470 W
dbgrp6 matrixih06(R) (CL1-E , 4, 5-0)31266 150..S-VOL SSUS,----- 137 W
what could be the problem?

Re: Create Business Copy
Hello
Following are the steps which are needed to configure a BC.
Create initial /etc/horcm file with correct HORCM_MON & HORCM_CMD information. Comment off all other values.
Start a Raid Manager instance as below:
# horcmstart.sh 0
# export HORCMINST=0
# export HORCC_MRCF=1
Run raidscan with the correct port option argument and find the correct TID & LUN information to put in the HORCM_DEV section.
# raidscan -p port_name -fx | more
Stop the raid manager instance as below.
# horcmshutdown.sh 0
Now create two instance files say /etc/ horcm10.conf (for P-Vol) and /etc/ horcm20.conf (for S-Vol). Create HORCM_DEV and HORCM_INST sections using the information displayed in the raidscan command.
Restart raid manager instance 10 and 20 as below.
# horcmstart.sh 10 20
# export HORCMINST=10
# export HORCC_MRCF=1
Run pairdisplay (pairdisplay -c) to check the correctness of the horcm file.
# pairdisplay -c -g group_name
Run pairdisplay to display the status of the volumes in the group designated with the -g option.
# pairdisplay -g group_name -fcx
Note: The status of S-Vol and P-Vol at this stage will be SMPL.
Run paircreate to create the pair.
# paicreate -g group_name -vl
Run pairdisplay to display the status.
# pairdisplay -g group_name -fcx
Note: The status of S-Vol and P-Vol at this stage will be COPY.
Once the pairdisplay show the status of the volumes in the group as "PAIR", split the pair with the following command.
# pairsplit -g group_name
Note: The status of S-Vol and P-Vol at this stage will be PSUS.
