occurs, is displayed. When the monitoring time" is "0 min.", the ETERNUS DX Disk storage system is not
being monitored. When the REC Buffer usage is "Unused", a "-" (hyphen) is displayed.
• HALT Wait Timer

stopped to give priority to performing REC Buffer transfers in a high-load state. When the REC Buffer usage
is "Unused", a "-" (hyphen) is displayed.
• I/O Priority Mode
Whether the "I/O Priority Mode" is enabled or disabled is displayed. A "-" (hyphen) is displayed when the
usage is "Unused".
"I/O Priority Mode" reduces the effect on host I/O when an initial copy for starting, restarting, or recovering
the copy function is performed.

• Immediate HALT Mode
Whether the "Immediate HALT Mode" is enabled or disabled is displayed. A "-" (hyphen) is displayed when

"Immediate HALT Mode" reduces the effect on host I/O because the REC Buffer is insufficient when "HALT
Wait Timer" is set to "0 sec.".
