Agent information 41
• Read Errors—Displays the total number of read memory parity errors that were detected while reading from the
Array Accelerator. The mirrored copy of data in the write cache can be accessed to obtain correct data if a
memory parity error occurs.
Memory parity errors occur when the system detects that information has not been transferred correctly. A parity
bit is included for each byte of information stored in memory. When the microprocessor reads or writes data,
the system counts the value of the bits in each byte. If the total does not match the system's expectations, a
parity error has occurred. A bad memory chip, memory corruption, or lack of memory refresh may cause
memory parity errors.
Identify Drives
Select the length of time to identify the physical drives that are connected to this controller from the drop-down list box
and then click the Start button. The page automatically refreshes and displays an image of an identified drive and a
Stop button. Click the Stop button to end identification before the time expires.
After the drive identification completes, the page must be refreshed manually to display the Start button. There may
be a delay, depending on the length of the HP Insight Management Agents data collection interval, after the drive
identification completes and before the Start button appears.
Only drives in hot plug trays are supported since the LEDs are part of the tray. If an individual logical drive or
physical drive on this controller is selected while the drives connected to this controller are currently identified, the
other drives stop identification and only the selected drive are identified.
When there are redundant controllers only the active controller can be used to identify the drives connected to the
controller.
IMPORTANT: The Start or Stop button only displays if you are logged on as an administrator or an operator,
SNMP Sets are enabled, and a SNMP Community string has been defined with 'write' access. Go back to the
Summary page and select login to login as an administrator or operator. SNMP Sets can be enabled in the HP
Insight Management Agents control panel applet on the SNMP Settings page. A SNMP Community string with
'write' access can be defined in the SNMP Service Properties Security page located in Computer Management
under Services. The drive icon does not blink in Microsoft Internet Explorer unless Play animations in web
pages is enabled in the Tools menu Internet Options under the Advanced tab in the Multimedia section.
Physical Drive Information
This section provides an overview of all disk drives attached to the controller. Each physical drive is listed as a
separate entry in the Mass Storage submenu. The information displayed next to the physical drive includes the
condition of the drive, the location of the drive and drive size. Select any of the physical drives from the Mass
Storage submenu to display more information about the drive.
The following information displays:
• Status—Indicates the status of the physical drive. The possible values are:
• OK—The drive is functioning properly.
• Failed—The drive is no longer operating and should be replaced.
• Predictive Failure—The physical drive has a predictive failure error and should be replaced.
• Erasing—The physical drive is currently being erased and in an offline state.
• Erase Done—The erase operation has completed and the physical drive is in an offline state.
• Erase Queued—An erase operation is currently queued for this physical drive.
• Unknown—The physical drive cannot be monitored at this time. This may be due to:
• The device driver for this drive may have been unloaded.
The logical drive may have failed and been deactivated by the operating system. In this case, the last
known status was OK.
The Storage Agents do not recognize the drive. You may need to upgrade your software.
• Action—Displays the action that is required for this device. The following values are valid:
• Replace Drive—Replace this drive. If the drive condition is Failed, check the Predictive Indicators, Problem
Indicators, and Failure Indicators for a possible cause of the failure.
• Replace S.M.A.R.T. Drive—The S.M.A.R.T. hard drive predicts imminent failure. Schedule replacement of the
drive before an actual failure occurs.
• No Action Required—The drive is operating normally and no action is required.
• Capacity—Displays the size of the physical drive.
