HP 3PAR StoreServ 7450 Storage Service Guide

NOTE: SSDs have a limited number of writes that can occur before reaching the SSD's write
endurance limit. This limit is generally high enough so wear out will not occur during the expected
service life of an HP 3PAR StoreServ under the great majority of configurations, input/output
patterns, and workloads. HP 3PAR StoreServ tracks all writes to SSDs and can report the percent
of the total write endurance limit that has been used. This allows any SSD approaching the write
endurance limit to be proactively replaced before they are automatically spared out. An SSD has
reached the maximum usage limit once it exceeds its write endurance limit. Following the product
warranty period, SSDs that have exceeded the maximum usage limit will not be repaired or replaced
under HP support contracts.
Identifying a Disk Drive
1. Under the Systems tree in the left panel of HP 3PAR Management Console, select the storage
system to be serviced. The Summary tab should be displayed indicating the failed drive (see
Figure 26 (page 25)).
Figure 26 Summary Tab
WARNING! The Physical Disks may indicate Degraded, which indicates that the disk drive
is not yet ready for replacement. It may take several hours for the data to be vacated; do not
proceed until the status is Failed. Removing the failed drive before all the data is vacated
will cause loss of data.
2. On the Summary tab, select the Failed link in the Physical Disk row next to the red X icon
( ).
CAUTION: If more than one disk drive is failed or degraded, contact your authorized service
provider to determine if the repair can be done in a safe manner, preventing down time or
data loss.
A filtered table displays, showing only failed or degraded disk drives (see Figure 27 (page
26)).
