Additional Options for Disks
Action Description
Locate
Toggle the locator indicator for the disk. If the LED is
currently turned on, this icon will be blinking.
Offline
Offline the disk. This option is only available for disks
that are part of a configured storage pool (including
the system pool). Offlining a disk prevents the system
from reading or writing to it. Faulted devices are already
avoided, so this option should only be required if a disk
is exhibiting performance problems that do not result in
pathological failure. It is not possible to offline a disk
that would prevent access to data (i.e. offlining both
halves of a mirror). If the device is an active hot spare,
this will also give the option of detaching the hot spare
completely. Once a hot spare is detached, it cannot be
activated except through another fault or hotplug event.
Note - Do not perform a pool configuration operation
while a disk firmware upgrade is occurring. To check
if an upgrade is in progress, navigate to Maintenance >
System in the BUI, or maintenance system updates in the
CLI.
Online
Online the disk. Reverses the above operation.
SSD Endurance
SSD endurance reports the remaining life expectancy of an SSD. Endurance properties are
reported on the BUI Maintenance > Hardware chassis details page and in the CLI maintenance
chassis disk context. You can set a threshold alert when an SSD exceeds a specified percentage.
For example, set an alert to occur when one or more SSD devices exceeds a 95% threshold.
For more information, see “Threshold Alerts” in Oracle ZFS Storage Appliance Administration
Guide, Release 2013.1.5.0.
You can use this feature to monitor the life expectancy of an SSD. For example, if SSD
endurance reports 50% after two years, the SSD is estimated to last for another two years,
assuming the workload is consistent.
Note - Do not use reported SSD endurance percentage as an indication to replace the SSD. SSD
warranty replacements are made only when a failure is reported.
