HP 3PAR StoreServ 7200 2-node Service Manual page 11

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, IO 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 5 (page 11)).
Figure 5 Summary Tab
NOTE: 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 recreated; do not
proceed until the status is Failed.
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
12)).
