2 Introduction to maxView Storage Manager
This section introduces the maxView Storage Manager software, explains the concept of “storage space” and provides a checklist of getting-started tasks.
3 Installing maxView Storage Manager
4 Exploring maxView Storage Manager
This section familiarizes you with the main features of the maxView Storage Manager graphical user interface. It describes how to start and login to maxView Storage Manager. It also explains how to get help and log out of maxView Storage Manager when you are finished working with the application.
5 Building Your Storage Space
6 Protecting Your Data
7 Modifying Your Storage Space
This section provides additional scenarios for creating and modifying arrays and logical drives. It explains how to check your logical drives for bad or inconsistent data; optimize controller and logical drive performance; move arrays and logical drives; and perform advanced operations, such as creating a split mirror backup array.

  - 12.4.1 Clearing Error Counters from a Physical Device
    Use this option to clear the device error counters of a specific physical device.
  - 12.4.2 Clearing Error Counters from a Controller
    Use this option to clear the device error counters of all the physical devices from controller.
- 12.5 Refresh SED Security Status
- 12.6 Working with Failed or Failing Disk Drives
- 12.7 Erasing a Disk Drive
- 12.8 Initializing and Uninitializing Disk Drives
  This section describes how to initialize/uninitialize disk drives to enable the erased drive, erase data and meta-data (including logical drive information) from the disk drives (and SSDs) in your storage space. You can initialize or uninitialize individual disks, or use the wizard to initialize/uninitialize all disks on a controller.
- 12.9 Setting the Physical Drive Boot Priority
  Use this option to set the boot priority of a physical device to Primary, Secondary, Primary and Secondary, or None (default). A controller can have only one physical (or logical) device as the primary or secondary boot device. When you select a new physical device as the primary/secondary boot drive, the boot priority of the existing primary/secondary boot drive is overwritten and set to None.

12.4 Viewing Physical Device Error Counters

To view the physical device error counters for a hard drive or SSD, select the drive in the Enterprise View then, on the Storage Dashboard, click the Error Counters tab. The table below describes the error counters.


Error Counter	Description
Aborted Command	Number of times a drive was failed due to aborted commands that could not be retried successfully.
Bad Target Error	Number of times that this drive did something that did not conform to the SCSI Bus Protocol. It will cause a reset of the SCSI bus that this drive is attached to.
ECC Recovered Read Errors	Number of ECC‑corrected read errors.
Failed Read Recover	Number of times a recover of another physical drive in the logical volume failed due to a hard read error from this drive.
Failed Write Recover	Number of times a recover of this physical drive failed due to an error occurring on this drive during a write operation.
Format Error	Number of times a Format command (used when remapping defects) failed. A failed remap operation may cause the controller to fail a drive.
Hardware Error	Number of times a drive returned a bad hardware status. The drive may be failed if retries do not work.
Hard Read Error	Number of unrecoverable read errors.
Hard Write Error	Number of unrecoverable write errors.
Hot-Plug Count	Number of times this drive was hot-plugged (removed) from a box.
Media Failure	Number of times a drive was failed due to unrecoverable media errors.
Not Ready Error	Number of times the drive was failed because it never became ready after the “spin up” command was issued. If retries or drive spin-ups fail, the drive will be failed.
Other Timeouts	Timeouts other than Data ReQuest Timeouts (DRQ).
Predictive Failure	Number of times that the drive returned a predictive failure error.
Retry Recovered Read Error	Number of retry‑recovered read errors.
Retry Recovered Write Error	Number of retry‑recovered write errors.
SCSI Bus Fault	Number of “bus faults”, which we define as SCSI bus parity errors, overrun/underrun conditions, etc.
Service Hours	Number of service hours since the last power cycle.
Sectors Written	Number of sectors written to media.
Sectors Read	Number of sectors read from the media. This value will include sectors read into the on-drive cache buffer only if the drive keeps track of this value. Otherwise, only sectors requested through the drive interface are counted.
