$ SET SHADOW/SITE=1 DSA0: $ ! $ ! Command sequence used on system 2 at site 2: $ MOUNT/SYSTEM DSA0:/SHADOW=($1$DGA0:,$1$DGA1:) TEST $ SET SHADOW/SITE=2 DSA0: $ ! $ ! Commands used on both system 1 and system 2: $ SET SHADOW/SITE=1 $1$DGA0: $ SET SHADOW/SITE=2 $1$DGA1: In this example, the system at site 1 will perform reads from $1$DGA0, which is located at that site, while the system at site 2 will perform reads from $1$DGA1, which is located at site 2. 2.$ SET SHADOW DSA1: /POLICY=HBMM= - _$ (MASTER_LIST=(NODE1,NODE2,NODE3), COUNT=2, - _$ RESET_THRESHOLD=75000) This command defines an HBMM policy for shadow set DSA1:. The policy specifies that no more than two systems of the three systems listed can have an HBMM master bitmap. Once 75000 blocks have been modified on DSA1:, any existing HBMM bitmaps are zeroed. 3.$ SET SHADOW /POLICY=HBMM=(MASTER_LIST= - _$ (NODE1,NODE2,NODE3), RESET_THRESHOLD=75000, COUNT=2) - _$ /NAME=HONESTY_IS_BEST This command defines the named policy HONESTY_IS_BEST. This policy is available to all cluster members, but is not applied to any specific shadow set. 4.$ SET SHADOW DSA1: /POLICY=HBMM=HONESTY_IS_BEST This command associates the named policy HONESTY_IS_BEST with shadow set DSA1. 5.$ SET SHADOW /POLICY=HBMM=( - _$ (MASTER_LIST=(NODE1,NODE2,NODE3), COUNT=2), - _$ (MASTER_LIST=(NODE4,NODE5,NODE6), COUNT=2), - _$ RESET_THRESHOLD=150000) - _$ /NAME=POLICY_2 This command defines the HBMM named policy POLICY_2, which has two master lists. 6.$ SET SHADOW DSA2: /POLICY=HBMM=POLICY_2 This command associates the named policy POLICY_2 with shadow set DSA2. 7.$ SET SHADOW /POLICY=HBMM /DELETE /NAME=POLICY_2 This command deletes the named policy POLICY_2. Note that any shadow set that had acquired the attributes of POLICY_ 2 by execution of a SET SHADOW DSAn: /POLICY=HBMM=POLICY_2 command is not affected. Changes made to a named policy are not retroactive to a mounted shadow set that was assigned the characteristics of a previous version of that named policy. 8.$ SET SHADOW DSA1: /POLICY=HBMM /DELETE This command deletes the existing HBMM policy from DSA1:. If this HBMM policy is enabled on DSA1:, you must first execute the following command to disable the policy before you can delete it: $ SET SHADOW DSA1: /DISABLE=HBMM 9.$ SET SHADOW /DEMAND_MERGE/CONFIRM Allow merge of _DSA721:? [N]:y Allow merge of _DSA850:? [N]: TRUE Allow merge of _DSA1010:? [N]:N $ In this example, a merge operation is initiated on DSA721: and DSA850: but not on DSA1010:. 10$ SET SHADOW DSA1/POLICY=HBMM=(MASTER=*,COUNT=12,MULTIUSE=12,DISMOUNT=1) In this example, a policy is set in which all 12 bitmaps can be used as multiuse bitmaps. When you execute the command DISMOUNT/POLICY=MINICOPY, 1 minimerge bitmap is converted to multiuse bitmap. You can use this multiuse bitmap with the MINICOPY command to add the dismounted member back to the shadow set. In other words, it specifies that 12 bitmaps can be used during the automatic and 1 bitmap during the manual removal of the shadow set member. 11$SET SHADOW DSA42 /STALL=WRITES In this example, the writes are stalled to the shadow set for a period of SHADOW_MBR_TMO seconds. 12$SET SHADOW DSA42 /STALL=WRITES=60 In this example, the writes are stalled to the shadow set for a period of 60 seconds. 13$SET SHADOW DSA42 /NOSTALL=WRITES=30 In this example, the writes are allowed to the shadow set after a period of 30 seconds.
