HP StorageWorks XP24000 Continuous Access Software User and Reference Guide, v01 (T5278-96002, June 2007)
Caution:
Limit the number of hosts connected to an RCU target port to 128 or fewer to avoid a
mistaken disconnection. If more than 128 hosts are connected to an ordinary target, some hosts may
be
disconnected af ter changing the type from target to RCU target.
To configure the storage system Fibre Channel por ts:
1. Click the RCU Operation tab, and click the Port display b ut ton to display the channel adapters
andporttypes forthe connected storagesystem in thetree.
2. Select the desired channel adapter to display only the ports for that channel adapter. Select
the
desired port type to display all ports of the selected t ype.
3. Select the port(s) that you want to configure. Makesuretoselectonly fibre ports.
4. Right-click the selected port(s), and then select the desired port t ype: initiator, RCU target, or
target for Fibre Channel. Modified is displayed on the right-most colum n of the selected port.
The preview list displays the updated information.
5. Verify the requested port change operation(s) displayed in the two lists.
To change one or more p ort operations, select the operation(s), right-click the upper list, and
select the desired p ort t ype. To remove one or more operations, select the operation(s), right-click
the
preview list, a nd click Delete. To cancel all operations, select all the operations in the
prev ie w list, r ight-click, and click the Delete command, or click the Cancel button.
WARNING:
Read and follow the important warnings and caution above before starting port
change operations.
6. To start the opera tion(s), click the Apply button.
Adding an RCU
You can add up to four RCUs to each MCU and establish up to eight p a ths to each RCU. You must
add
each CU as a separate RCU to each CU of the MCU. The logical paths are established for the
CUs of the MCU and RCU separately. The maximum number of logical paths for each MCU is 32 (8
paths
pe
rRCU ×4RCUs perMCU).
Theremotecopyconnections andMCU portsmustbeproperlyinstalled andconfigured b efore you can
add an
RCU. When you add an RCU, the selected CU of the connected MCU adds the specified CU
as a Continuous Access RCU and establishes the specified num b er of log ical paths to the RCU. After
you hav
e
added an RCU (and path status is normal), you can create Continuous Access pairs which
have S-VOLs in the newly added RCU.
The Add RCU dialog box (see Figure 26 on pa ge 72) allows you to add an RCU to the selected CU
of the connected MCU. To open the Add RCU d ialog box, select the MCU&RCU display on the RCU
Opera
tion
window, select the desired CU in the tree, right-click the list, select the RCU Operation
command, and then select the Add RCU command.
Note
: If you have already added four RCUs (the maximum number of RCUs that you can add to an
MCU),
the Add
RCU command does not take effect and you cannot click the command.
Note
: When you add an RCU to a CU on the storage system, you cannot use CU Free. You must
specify a CU when you add an RCU.
