Table 53 Restrictions for Connecting an EMC CLARiiON CX Series

Version	Restrictions
60-04-04-00/00 and higher, and lower than	The RAID-6 volume for the EMC CLARiiON CX series can
60-06-00-00/00	be used by installing the profile for supporting the RAID-6
	volume for the EMC CLARiiON CX series.
	However, the RAID-6 volume and the other RAID volume
	cannot be defined in the same port. Either the RAID-6
	mapping volume or the other RAID type mapping volume
	might be blockaded when those volumes are added in the
	same port.
	The RAID-6 volume and the other RAID volume that are
	defined in separate ports are displayed as different devices.
60-06-00-00/00 and higher	The RAID-6 volume and the other RAID volume can be
	defined and mapped in the same port.
	The volume that is mapped by a storage system lower than
	60-06-00-00/00 can be continuously used. However, the
	volumes that have been displayed as different devices are
	displayed as one device.
	NOTE: The RAID-6 mapping volume is blockaded without
	exception when you downgrade a storage system to a
	version lower than 60-06-00-00/00. Therefore, delete the
	RAID-6 volume when you downgrade a storage system.
	After the downgrade, the restrictions described in the
	column for 60-04-04-00/00 and higher, and lower than
	60-06-00-00/00 in this table are applied. Change the
	definition to the other port when the RAID-6 volume and
	the other RAID volume are defined in the same port.

System Option mode

When you connect an EMC CLARiiON CX series as an external storage system, set system option mode 725 of the local storage system. If system option mode 725 is not set, the external storage system might be blocked when performing maintenance, including rebooting the controller of the external storage system by the firmware update and so on. For instructions about setting system option mode 725, contact HP

EMC Symmetrix Series

If you have or plan to have EMC logical devices with addresses over FFF provisioned to a storage system, to display these addresses correctly in the Characteristic1 field in the External Volumes list on the Volume Operation window, you must do the following:

Procedure 1

1.Check the EMC Symmetrix SCSI flags listed on the EMC Command Center Display for the EMC adapters that are connected to or will be connected to the storage system external ports. Ensure that the SC3 flag is enabled and the SPC2 flag is disabled.

2.Set SOM 745 to ON. An HP-authorized support person is required to do this service action from the SVP.

3.In the Path Operation tree on the Path Operation window (see “Path Operation Window” (page 55)), perform the CheckPaths operation for paths that are already mapped. An alternate method is to wait at least 1 hour, and then the device health check is automatically performed.

4.After processing, click Refresh to update the Characteristic1 field. The volumes with EMC logical device addresses over FFF will display correctly.

If CheckPaths is performed while a ShadowImage for Mainframe pair and an HP StorageWorks XP for FlashCopy Mirroring Software pair are defined in the specified volume, the CheckPaths operation is rejected with a 605 2518 message. If a ShadowImage for Mainframe pair and a FlashCopy Mirroring pair are defined in the specified volume, do not perform CheckPaths, but wait for the device health check to automatically update the Characteristic1 field.
