CAUTION:
Before issuing the CESTPATH command, verify that the relevant paths are offline from the
host(s) (for example, configure the Chipid offline, 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.
NOTE:
For Fibre Channel interface, do not use the CESTPATH and CDELPATH commands at the same
time as the SCSI path definition function of LUN Management. The Fibre Channel interface ports need to
be configured as initiator ports or RCU target ports before the CESTPATH and CDELPATH commands are
issued.
The following table describes the CESTPATH LINK parameter for serial and Fibre Channel interface.
The following table gives the XP128/XP1024/XP10000/XP12000 system adapter ID (SAID) values for the
CESTPATH LINK parameter.
•
The last two digits of the link parameter must specify the logical CU number (00-1F for an
XP128/XP1024/XP10000/XP12000, 00-0F for an XP256).
•
For 3990 controller emulation, the first two digits can be 00, 01, or 02. This option controls freeze as
follows:
00 = use mode 104
01 = freeze enabled
02 = freeze disabled
