Symptoms
嘗試執行下列命令：
symrcopy -file filename.txt create -copy -name COPY_NAME -pull -hot -nop 'Create' operation execution is in progress for the device list in device file 'filename.txt'. Please wait... The REMOTE Copy 'CREATE' operation FAILED. (SYMAPI_C_RCOPY_DISCOVER_ERROR) An rcopy remote device discover error occurred
在 SYMAPI 記錄中：
STARTING a RCOPY 'CREATE' operation. Symm 000xxxxxxxxx Ctrl-Rem Devices: [ 0xxx-xxxxxxxxxxxxxxxx ] 217 EMC:SYMRCOPY checkForCreateFailur Create failed on dev:0xxxx, sid:000xxxxxxxxx, status:loc_sts:0x8 SYSC_SESSION_DISCOVER_FAILED 217 EMC:SYMRCOPY map_discover_errors rem_num:0, rem_sts:0x19SANCOPY_DEV_INVALID_BLOCK_SIZE 217 EMC:SYMRCOPY checkForCreateFailur Discover failed on dev:0xxxx, sid:000xxxxxxxxx, status:7140 The RCOPY 'CREATE' operation FAILED with: An rcopy remote device discover error occurred
Cause
發生此問題是因為 XIO 裝置上的區塊大小為 4096。可使用 "symsan list -sanluns" 命令輸出會顯示裝置的區塊大小：
Symmetrix ID: 000xxxxxxxxx
Remote Port WWN: xxxxxxxxxxxxxxxx

------ -- ------- ----- -------- ----- ----- - --------------------------------
01D:09 RW ... F.. 4096 10240 1 N/A - xxxxxxxxxxxxxxxxResolution
此為設計運作方式。Open Replicator 不支援 4096 區塊大小的裝置。
