REPLICATE SERVER - CLARiiON to DMX

To replicate a host from CLARiiON to DMX pool. You first need to gather host CX HLU/ALU pairs.

# navicli -h $myspa storagegroup -list -gname $mysg 
  HLU Number     ALU Number
  ----------     ----------
    0               1008
    1               103
    2               201
    3               210
    4               204

See list of existing devices in RPA storage group.

# navicli -h $myspa storagegroup -list -gname RPC1_RPA_1_2_3_SG
 HLU Number     ALU Number
  ----------     ----------
    0               2410

Add LUNs into RPA storage group.

# navicli -h $myspa storagegroup -addhlu -gname RPC1_RPA_1_2_3_SG -hlu 1 -alu 1008
# navicli -h $myspa storagegroup -addhlu -gname RPC1_RPA_1_2_3_SG -hlu 2 -alu 103
# navicli -h $myspa storagegroup -addhlu -gname RPC1_RPA_1_2_3_SG -hlu 3 -alu 201
# navicli -h $myspa storagegroup -addhlu -gname RPC1_RPA_1_2_3_SG -hlu 4 -alu 210
# navicli -h $myspa storagegroup -addhlu -gname RPC1_RPA_1_2_3_SG -hlu 5 -alu 204

Get block size on CX LUN.

# navicli -h $myspa getlun 1008 | grep Blocks
LUN Capacity(Blocks):       104857600

Build TDEVs file, the CX Block Size / 1917.873 equals required TDEV Block Size.

# cat tdev_src.txt
create dev count=1, size=54674 cyl, emulation=FBA, config=TDEV, preallocate size=54674 cyl, binding to pool = FIBRE_1997_1;
create dev count=4, size=21870 cyl, emulation=FBA, config=TDEV, preallocate size=21870 cyl, binding to pool = FIBRE_1997_1;

Configure TDEVs.

# symconfigure -sid $mysid -f tdev_srv.txt preview
# symconfigure ....

Map and Mask TDEVs to remote RPA; see my DMX GORUN script to automated that task.

Configure RPA for replication. See the Recovery Point Tasks for setting up replication.

SPLIT REPLICATION, MOUNT FILE SYSTEM

This procedure shows you how to stop an active RecoverPoint replication and mount the file systems on the remote site.

Review server source file system and disk information.

# vxdisk -o alldgs -e list
emcpower20s2 auto:cdsdisk    RPC1_test01  RPC1_test    online
emcpower21s2 auto:cdsdisk    RPC1_test02  RPC1_test    online

# syminq | egrep '20c|21c'
/dev/rdsk/emcpower20c        DGC       RAID 5       0326 7E000010    104857600
/dev/rdsk/emcpower21c        DGC       RAID 5       0326 9C000015    104857600

Confirm those source LUNs in RecoverPoint i.e. LUN 126 (7E) and 156 (9C).
