Symptoms of this issue are: • Data replication stops after the upgrade. • There are no visible paths to the destination array. To determine if there are visible paths, select the Data Replication folder in the HP P6000 Command View navigation pane. When the Data Replication Properties Folder window opens in the content pane, select View remote connections. To resolve this issue, you must set the protocol to HP FC Data Replication Protocol in HP P6000 Command View as follows: 1. Select the upgraded array in the EVA Storage Network Properties window. 2. Select the Data Replication folder in the navigation pane. The Data Replication Properties Folder window opens in the content pane. 3. Select Data Replication Options. The Data Replication Options window opens. 4. Select Set Data Replication Protocol. The Data Replication Protocol options window opens. 5. Select HP FC Data Replication Protocol. 6. Select Save Changes. DR log progress bar percentage appears incorrect Because the DR log can suddenly reach the full copy threshold, the percentage complete displayed by HP P6000 Command View can appear to be inaccurate. This is caused by overhead (or metadata) that is applied to the file and is included in the percent complete, which reduces the amount of capacity available. This overhead is more significant for smaller log files than larger log files because some of the overhead is constant in size. For example, a 5 GB minimum log size can contain 35 percent overhead, while a 40 GB log file might only contain 10 percent overhead. This could cause the progress bar in HP P6000 Command View to show a larger amount of progress than one would expect for the allocated log size. Creating disk groups with double protection level When creating a disk group with double protection level on an array running XCS 10001000, a minimum of 10 disk drives is required on the array. If the disk group contains fewer than 10 drives and double protection is requested, only single protection level will be used. If all the physical disks in the disk group are of the same capacity, double protection level is achieved by reserving capacity equal to four times the capacity of a single disk. If the physical disks in the disk group are of different capacities, double protection is achieved by reserving capacity equal to the sum of the four highest capacity disks.

Citrix 5.6 host may require manual rescan If you have a Citrix 5.6 host running Emulex 4 Gb/8 Gb HBAs in a direct connect configuration, you may need to perform a manual rescan after adding or removing LUNs online.
