This section explains the operation methods of following processes.
Execution of first backup
Use "A.6.1 acopc start (OPC/QuickOPC copy start command)" to execute backups via QuickOPC.
For the first QuickOPC, execute "A.6.1 acopc start (OPC/QuickOPC copy start command)" without specifying the -diff option.
[Execution example]
> acopc start -g QuickOpcGroup E4000/0x1:E4000/0x3 # DATE : 2008/06/25 00:00:00 - << Differential OPC Started >> # From:BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=1/Adr_high=0/Adr_low=0/size_high=0/size_low=0 # To :BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=3//Adr_high=0/Adr_low=0 E4000/0x2:E4000/0x4 # DATE : 2008/06/25 00:00:02 - << Differential OPC Started >> # From:BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=2/Adr_high=0/Adr_low=0/size_high=0/size_low=0 # To :BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=4/Adr_high=0/Adr_low=0 Succeeded : 2 Failed : 0 |
Executing the first QuickOPC starts a tracking process as well as an OPC from the copy source volume to the copy destination volume.
Figure 3.1 What happens when the "acopc start" command is executed (for the first time)
Check the backup execution status
The execution status of the backup can be checked by using "A.6.2 acopc query (OPC/QuickOPC copy status display command)" in the same way as for backups via OPC.
[Execution example]
> acec query -g QuickOpcGroup Copy Group Name : QuickOpcGroup Copy Group Type: QuickOPC Disk Array Name : E4000 (00E4000M3#####E450S20A####KD4030639004##) Source <=> Target SID OPC Status Copy Phase Copied Block --------- --- --------- ---- --------------- ------------------ ------------ E4000/0x1 ==> E4000/0x3 0x21 "OPC Executing" "Copying/Tracking" 6912 E4000/0x2 ==> E4000/0x4 0x22 "OPC Executing" "Copying/Tracking" 5760 |
Check the QuickOPC copy progress status
The QuickOPC copy progress status of the backup can be checked by specifying the -progress option for "A.6.2 acopc query (OPC/QuickOPC copy status display command)".
This function can be used in Windows version only.
[Execution example]
> acopc query -g QuickOpcGroup -progress Copy Group Name : QuickOpcGroup Copy Group Type : QuickOPC Disk Array Name : E4000 (00E4000M3#####E450S20A####KD4030639004##) Source <=> Target Progress Copied Block Total Block --------- --- --------- -------- ------------ ----------- E4000/0x1 ==> E4000/0x3 1% 6912 1048576 E4000/0x2 ==> E4000/0x4 1% 5760 1048576
When the physical copy of QuickOPC finishes, only the tracking process will still be running.
Figure 3.2 What happens when the snapshot processing finishes
Check the tracking status
The tracking status can be checked using "A.6.2 acopc query (OPC/QuickOPC copy status display command)".
[Execution example]
> acec query -g QuickOpcGroup Copy Group Name : QuickOpcGroup Copy Group Type: QuickOPC Disk Array Name : E4000 (00E4000M3#####E450S20A####KD4030639004##) Source <=> Target SID OPC Status Copy Phase Copied Block --------- --- --------- ---- --------------- ---------- ------------ E4000/0x1 ==> E4000/0x3 0x21 "OPC Executing" "Tracking" 1048576 E4000/0x2 ==> E4000/0x4 0x22 "OPC Executing" "Tracking" 1048576 |
Execution of backup for the second or subsequent time
If the "A.6.1 acopc start (OPC/QuickOPC copy start command)" is executed with the -diff option specified while the tracking processing is running, only the differential data updated since the last OPC will be copied, which means that copies take less time to complete.
[Execution example]
> acopc start -g QuickOpcGroup -diff E4000/0x1:E4000/0x3 # DATE : 2008/06/26 00:00:00 - << Differential OPC Started >> # From:BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=1/Adr_high=0/Adr_low=0/size_high=0/size_low=0 # To :BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=3/Adr_high=0/Adr_low=0 E4000/0x2:E4000/0x4 # DATE : 2008/06/26 00:00:02 - << Differential OPC Started >> # From:BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=2/Adr_high=0/Adr_low=0/size_high=0/size_low=0 # To :BoxID=303045343030304d3323232323234534353053323041232323234b44343033303633393030342323/Olu=4/Adr_high=0/Adr_low=0 Succeeded : 2 Failed : 0 |
