global copy 概念及配置

配置global copy 就三步:

Determine the available Fibre Channel links

Define paths for Global Copy

Create Global Copy pairs

 

第一步:Determining the available Fibre Channel links

FCP port ID with the lsavailpprcport command has four hexadecimal characters in the
format 0xEEAP, where EE is a port enclosure number (00–3F), A is the adapter number
(0–F), and P is the port number (0–F). The FCP port ID number is prefixed with the letter I.

You need the worldwide node name (WWNN) of your target DS8000 to issue the
lsavailpprcport command. You can get this by using the lssi command; see Example 16-5.
You have to issue this command to the DS HMC connected to DS8000#2, which is the Metro
Mirror target.

第二步:Creating Metro Mirror paths

Now you can use the mkpprcpath command to create paths between the source and target
LSSs and then verify the result with an lspprcpath command. You have to issue the
mkpprcpath command for each LSS pair;

dscli> mkpprcpath -remotedev IBM.2107-75ABTV1 -remotewwnn 5005076303FFC663 -srclss 10 -tgtlss 20 i0143:i0010 i0213:i0140

You can check the status of Global Copy using the lspprc -l command. Out Of Sync Tracks
shows the remaining tracks to be sent to the target volume (the size of the logical track for the
FB volume for the DS8000 is 64 KB). You can use the lspprc -fullid command flag to
display the fully qualified DS8000 storage image ID in the command output.

Remove Global Copy environment using DS CLI

Step 1: Remove Global Copy pairs

rmpprc command removes a volume pair relationship;

You can use the -quiet parameter to turn off the confirmation prompt for this command.

You can add the -at tgt parameter to the rmpprc command to remove only the available
Global Copy target volumes,You have to issue this command to the HMC connected to DS8000#2, which is the Global Copy target.

the Global Copy source volume status after the rmpprc -at tgt command has completed and it also shows the result of a rmpprc -at src command. In this case, there were still available paths. Therefore, the source volume state changed after the rmpprc -at tgt command completed. If there were no available paths, the state of the Global Copy source volumes would have been preserved

Step 2: Remove logical paths

The rmpprcpath command removes the paths. Before removing the paths, you must remove
all volume pairs that are using the paths, or you have to use the -force parameter with the
rmpprcpath command.
