CESTPATH

The CESTPATH command allows you to establish remote copy paths for the XP disk array. For
fibre, the RCU controller ID is specified. The syntax for the CESTPATH command (ESCON Interface)
is:
For 3990-6 and -6E controller emulations (Host Interface: ESCON):
CESTPATH:

DEVN(X'dev#') PRIM(X'ssid' serial#) SEC(X'ssid' serial#')
LINK(X'aabbccdd')

For 2105 and 2107 controller emulation (Host Interface: ESCON or FICON) ('lss' parameter for
LCU no., CGROUP and RESETHP options):
CESTPATH:

DEVN(X'dev#') PRIM(X'ssid' serial# X'lss') SEC(X'ssid' serial#' X'lss')
LINK(X'aabbccdd')
[CGROUP(YES|NO) RESETHP(YES|NO)]

For 2105 or 2107 emulation, use the CESTPATH CGROUP option to control freeze. Do not use
the SVP RCU FREEZE option (Mode 104) or the FREEZE option in CESTPATH LINK parameter. If
you use the FREEZE option, the CESTPATH command will be rejected.

CAUTION:

Before issuing the CESTPATH command, you must make sure that the relevant paths

are offline from the host(s) (for example, configure the Chipid offline, or deactivate the LPAR, or
block the port in the ESCD). If any active paths still exist, the add path operation will fail because
the port mode cannot be changed.

Do not use the CESTPATH and CDELPATH commands at the same time as the SCSI path definition
function of LUN Manager. The Fibre Channel interface ports need to be configured as initiator
ports or RCU target ports before the CESTPATH and CDELPATH commands are issued.

“CESTPATH LINK Parameter ” (page 197)

describes the CESTPATH LINK parameter for Fibre Channel

interface.
