[. . . ] CAUTION: See Pairresync operations for important information on performing quick restore operations on Cache LUN volumes. Continuous Access XP Journal volumes can be assigned to BC pairs, and BC volumes can be assigned to Continuous Access XP Journal pairs. Continuous Access XP volumes can be assigned to BC pairs, and BC volumes can be assigned to Continuous Access XP pairs. See Combining BC and Continuous Access XP operations for important information on BC and Continuous Access XP shared volume configurations. However, if the BC P-VOL is already paired with three S-VOLs, delete the BC pairs before migrating the volumes. Also, to assign BC volumes to destination migration volumes or reserve BC volumes for Auto LUN, delete the BC volumes or unreserve the BC volumes before using them with Auto LUN. If you assign a BC P-VOL that is already paired with three S-VOLs to Auto LUN migration volumes, or assign BC volumes to Auto LUN volumes other than migration volumes, the command will be rejected. If you split the BC pair assigned to Auto LUN migration volumes, migration of those volumes will be canceled. NOTE: You cannot use Auto LUN migration, destination, and reserved volumes for BC pair operations (the command will be rejected). To use Auto LUN volumes for BC pair operations, use Auto LUN to release the volumes. BC operations can be performed with External Storage XP operations to create pairs with the external volumes. Combining BC and Continuous Access XP Journal operations Continuous Access XP Journal volumes can be assigned to BC pairs, and BC volumes can be assigned to Continuous Access XP Journal pairs. Business Copy XP user guide 45 BC and Continuous Access XP Journal can function together in the same Local disk array to provide both internal and remote backup for your important data. NOTE: · A primary volume (P-VOL) of Continuous Access XP Journal means a primary data volume of Continuous Access XP Journal. A secondary volume (S-VOL) of Continuous Access XP Journal means a secondary data volume of Continuous Access XP Journal. · Combining BC L1 and L2 pairs with Continuous Access XP Journal volumes is allowed. Continuous Access XP Journal considers node and leaf volumes as secondary volumes (S-VOLs). The configuration shown in Figure 15 is an example of a volume that functions as both a Continuous Access XP Journal P-VOL and a BC P-VOL. This configuration allows you to: · Use BC to provide on-site backup copies of Continuous Access XP Journal P-VOLs · Use Continuous Access XP Journal to provide remote backup copies of BC P-VOLs Figure 15 BC and Continuous Access XP Journal: Shared P-VOL and P-VOL CAUTION: When you share a BC P-VOL with a Continuous Access XP Journal S-VOL as shown in Figure 16, the write operation to the Continuous Access XP Journal P-VOL takes time. Especially, when the BC pair is in the PSUS(SP) status, the write operation to the Continuous Access XP Journal P-VOL may take extra time due to the time for copying to the BC pair. In addition, if the journal volume size is small, the Continuous Access XP Journal pair may be suspended and fail due to a shortage of the capacity of its journal volume. The configuration shown in Figure 16 is an example of a volume that functions as both a Continuous Access XP Journal S-VOL and a BC P-VOL. This configuration allows you to use BC to provide remote copies of Continuous Access XP Journal S-VOLs. 46 Business Copy XP (BC) for the Array Figure 16 BC and Continuous Access XP Journal: Shared P-VOL and S-VOL Figure 17 is an example of a volume that functions as both a Continuous Access XP Journal P-VOL and a BC P-VOL, while the S-VOL of the same Continuous Access XP Journal pair also functions as the P-VOL of another BC pair. This configuration allows you to: · Use BC to provide on-site backup copies of Continuous Access XP Journal P-VOLs and S-VOLs · Use Continuous Access XP Journal to provide remote backup of BC P-VOLs Figure 17 BC and Continuous Access XP Journal: Shared P-VOL and P-VOL and P-VOL and S-VOL NOTE: In the configuration shown in Figure 17, you cannot perform the Business Copy XP and Continuous Access XP Journal copy operations at the same time. [. . . ] No more pairs can be created for the specified P-VOL. Corrective Action Call HP technical support for assistance. Delete any Reserve volumes. 1012 1013 1014 1015 1016 1017 101E 1026 Set one or more Reserve volumes. Delete some of the pairs of root volume. 1027 Delete some of the pairs of node volume. 1028 Confirm a pair condition. 1029 Confirm a pair condition. 102E 102F 1030 1031 1032 Confirm a matching condition. Delete any pairs formed by the P-VOL. Business Copy XP user guide 81 Error Code 1033 1037 103A 103B Description The specified P-VOL is not really a P-VOL. [. . . ]
