Script symbols
Symbols can be used in a script to enhance or limit the power of each script command. The following table
lists and describes the symbols that can be used in a script.
Operation macro commands
The functional macros are the script equivalents of the following TC390 pair operations:
• Create pairs (see page 195)
• Delete pairs (see page 197)
• Suspend pairs (see page 198)
• Resume pairs (see page 199)
• Change pair options (see page 200)
• Start pairs (see page 201)
• Get pair status (see page 201)
• Select pair devices (see page 201)
Create pairs
Use the CreateHrcPair command to establish new TC390 volume pairs.
NOTE: The CreateHrcPair command only creates the pair. You must run the StartHrcPair command after
establishing the pair to start the remote copy process.
The CreateHrcPair parameters are:
• M-VOL device list (numeric): C x 0x100 + VV, where C=CU#, VV=vol# within CU.
• Serial number list (string): RCU serial number (serial number is five digits decimal 0-9). Do not specify
more than 12 RCUs.
• SSID number list (numeric): RCU SSID (four digits hexadecimal 0-F).
• R-VOL device list (numeric): C x 0x100 + VV, where C=CU#, VV=vol# within CU.
• Initial copy pace list (string): “CP_MIDDLE” = 3 tracks; “CP_FAST” = 15 tracks; default = CP_FAST.
• Initial copy mode list (string): “E” = entire; “N” = none; default = E.
• Sync level list (string): “S0” or “Synchronous0” = sync, “S2” or “Synchronous2” = async; default = S0.
S0 and S2 cannot be specified at the same time.
