PowerScale OneFS Web Administration Guide
Chassis and drive states
You can view chassis and drive state details.
In a cluster, the combination of nodes in different degraded states determines whether read requests, write requests, or both work. A cluster can lose write quorum but keep read quorum. OneFS provides details about the status of chassis and drives in your cluster. The following table describes all the possible states that you may encounter in your cluster.
| State | Description | Interface | Error state |
|---|---|---|---|
| HEALTHY | All drives in the node are functioning correctly. | Command-line interface, web administration interface | |
| L3 | A solid state drive (SSD) was deployed as level 3 (L3) cache to increase the size of cache memory and improve throughput speeds. | Command-line interface | |
| SMARTFAIL or Smartfail or restripe in progress | The drive is in the process of being removed safely from the file system, either because of an I/O error or by user request. Nodes or drives in a smartfail or read-only state affect only write quorum. | Command-line interface, web administration interface | |
| NOT AVAILABLE | A drive is unavailable for a variety of reasons. You can click the bay to view detailed information about this condition.
NOTE In the web administration interface, this state includes the
ERASE and
SED_ERROR command-line interface states.
|
Command-line interface, web administration interface | X |
| SUSPENDED | This state indicates that drive activity is temporarily suspended and the drive is not in use. The state is manually initiated and does not occur during normal cluster activity. | Command-line interface, web administration interface | |
| NOT IN USE | A node in an offline state affects both read and write quorum. | Command-line interface, web administration interface | |
| REPLACE | The drive was smartfailed successfully and is ready to be replaced. | Command-line interface only | |
| STALLED | The drive is stalled and undergoing stall evaluation. Stall evaluation is the process of checking drives that are slow or having other issues. Depending on the outcome of the evaluation, the drive may return to service or be smartfailed. This is a transient state. | Command-line interface only | |
| NEW | The drive is new and blank. This is the state that a drive is in when you run the isi dev command with the -a add option. | Command-line interface only | |
| USED | The drive was added and contained a PowerScaleGUID but the drive is not from this node. This drive likely will be formatted into the cluster. | Command-line interface only | |
| PREPARING | The drive is undergoing a format operation. The drive state changes to HEALTHY when the format is successful. | Command-line interface only | |
| EMPTY | No drive is in this bay. | Command-line interface only | |
| WRONG_TYPE | The drive type is wrong for this node. For example, a non-SED drive in a SED node, SAS instead of the expected SATA drive type. | Command-line interface only | |
| BOOT_DRIVE | Unique to the A100 drive, which has boot drives in its bays. | Command-line interface only | |
| SED_ERROR | The drive cannot be acknowledged by the
OneFS system.
NOTE In the web administration interface, this state is included in
Not available.
|
Command-line interface, web administration interface | X |
| ERASE | The drive is ready for removal but needs your attention because the data has not been erased. You can erase the drive manually to guarantee that data is removed.
NOTE In the web administration interface, this state is included in
Not available.
|
Command-line interface only | |
| INSECURE | Data on the self-encrypted drive is accessible by unauthorized personnel. Self-encrypting drives should never be used for non-encrypted data purposes.
NOTE In the web administration interface, this state is labeled
Unencrypted SED.
|
Command-line interface only | X |
| UNENCRYPTED | Data on the self-encrypted drive is accessible by unauthorized personnel. Self-encrypting drives should never be used for non-encrypted data purposes.
NOTE In the command-line interface, this state is labeled
INSECURE.
|
Web administration interface only | X |
