Figure 7-3 Example for the one-host configuration
Operation authority with CMD security enabled
If the CMD security is enabled, you have the operation authority for the LU
which meets both of the following requirements.
• The connection to the host has been recognized when you start CCI.
• The LU is the target of the pair operation specified with MU# which is
defined in the configuration definition file.
For the volumes that you do not have the operation authority, "****" is
displayed as the LDEV#, and "----" is displayed as the status. If you perform
the pair operations, CCI rejects the request with the error code "EX_ENPERM"
(pairdisplay is not included).
If you specify 0, 1 2... for the MU#, your operation authority is limited on the
LUs for the local copy program products (ShadowImage, ShadowImage for
Mainframe and Copy-on-Write Snapshot). If you specify h0, h1 or h2 for the
MU#, your operation authority is limited on the LUs for the remote copy
operations (TrueCopy, TrueCopy for Mainframe, TrueCopy Async, Universal
Replicator, Universal Replicator for Mainframe, and global-active device). If
you specify nothing for the MU#, you have the operation authority on MU#0
for the local copy and the remote copy operations.
Target commands for protection
The following commands are controlled by the Data Protection
Facility: horctakeover, paircurchk, paircreate, pairsplit, pairresync,
pairvolchk, pairevtwait, pairsyncwait, raidvchkset, raidvchkdsp,
pairdisplay. When the command is issued to non-permitted volumes, CCI
rejects the request with error code "EX_ENPERM" (pairdisplay is not
included).
