I 2. To remove the failsafe lock from a remote copy set and resume normal operation, issue the

following CLI command:

SET RemoteCopyName ERROR_MODE=NORMAL

Example: set rcs1 error_mode=normal

You can also use this procedure for remote copy sets where a disaster-tolerant (DT) condition

is not required.

Note: If the error mode is set to normal and there is no target member, the remote copy set is no

longer considered DT.

Create Write History Log Units and Association Sets (Optional)

In the examples in this section, hypothetical disks 50100 and 60100 are the mirrorset for the

log disk. The write history log unit is MIR_D1LOG. The association set name is AS_D1. The

association set uses remote copy set name RCS1.

Create a Write History Log Unit

1. Create a mirrorset for the write history log disk:

ADD MIRRORSET MirrorsetName DiskName1 DiskName2

Example: add mirrorset mir_d1log disk50100 disk60100

Note: If you use scripting to automate failover and failback operations, do not use dashes

(hyphens) as separators in your naming convention—use underscores instead. Dashes are not

allowed by the Perl scripting language.

To minimize the number of devices used for logging, you can create and use one-member

mirrorsets. The logged data is not protected because it is written only to one disk. However, all of

this data is also written to the initiator unit. In the case of a log disk failure, you would incur a full

normalization, rather than a mini-merge, when access to the target is reestablished. The command

to create a one-member mirrorset is the same as that above, except only one disk is listed.

Example: ADD MIRRORSET MIR_D1LOG DISK 50100.

I 2. Initialize the mirrorset:

INITIALIZE MirrorsetName

Example: initialize mir_d1log

I 3. Verify that you have created a mirrorset:

SHOW StoragesetType

Example: show mir_d1log

You should see a display similar to that in Example Display 35.
