Display The Fibre Channel Connection Information Table; Pprcopy Delpair - IBM System storage DS6000 Series Redbook

14.3.2 Display the Fibre Channel Connection Information Table

The ANALYZE command allows the user to specify the WWNN of the secondary Metro Mirror
volume connected by Fibre Channel links. The analyze pathing reports include the Fibre
Channel Connection Information Table. This information indicates the potential connectivity
of the Fibre Channel ports in the DS6000 where the I/O is issued to each system adapter port
in the DS6000 that is specified by the secondary WWNN.
For example, consider the command shown in Example 14-15.
Example 14-15 ANALYZE NODRIVE NOSCAN command
//IKJEFT01 JOB MSGLEVEL=(1,1),MSGCLASS=A,NOTIFY=user id
//STEP01
//SYSPRINT DD SYSOUT=*
//VOL1
//SYSIN
ANALYZE DDNAME(VOL1) NODRIVE NOSCAN SECWWNN(500507630EFFFCA0)
This command in Example 14-15 generates the table seen in Example 14-16 that shows that
volume DS6030 with WWNN=500507630EFFFC6F can potentially connect to a device with
WWNN=500507630EFFFCA0 from:
PRI SAID 0000 through secondary SAID 0000 and 0100
PRI SAID 0100 through secondary SAID 0000 and 0100
Example 14-16 ANALYZE NODRIVE NOSCAN command output

14.3.3 PPRCOPY DELPAIR

The DELPAIR command is used to specify a Metro Mirror pair that will be removed from a
Metro Mirror relationship, thus returning the devices to a simplex state. See Example 14-17
on page 160.
