Description

This article describes the procedure that should be followed to replace a faulty hard disk drive on a SteelStore 2030 or 3030 appliance. 

Note:

  • NetApp recommends backup and restore activities be paused and cloud replication queue drained to 0MB (Reports › Optimization › Replication) before initiating any maintenance activity, to ensure the backup data is protected against unforseen complications.
  • Wait until the replacement is available on-hand before pulling a failed disk or power supply. The replacement needs to be inserted quickly to avoid disrupting the airflow and causing isolated thermal hotspots.
  • Legacy xx10 hardware such as the 3010 will automatically initiate a RAID rebuild upon replacement of a faulty disk.
  • The replacment disks include an attached tray/caddy.A torx T22 driver may be needed to unlock the disk's latch so it can be removed from the slot.
Disk FRU part numbers
SS730   (2TB) HDD-008 (Mfg WD2001FYYG)
SS2030 (2TB) HDD-008 (Mfg WD2001FYYG)
SS3030 (4TB) HDD-009 (Mfg WD4001FYYG)
 
Constant Data Integrity Check

To minimize the time necessary to rebuild the RAID array, stop the Constant Data Integrity Check (Reports › Diagnostics › Constant Data Integrity Check).
This is a low priority process that scavenges disk i/o to perform md5 checksums of data on the local disks and can starve the RAID rebuild operation of disk i/o.
 
Replacing multiple disks

If multiple disks have failed, replace the lowest numbered disk first and let it finish rebuilding before proceeding to the replace the next disk.
  • Using the standard slot numbering (disk0-diskn), choose the disk to be replaced that resides in lowest numbered slot.
  • Replace that disk as usual.
  • Do not replace any other disk until that disk has finished rebuilding.
  • Once that disk has finished rebuilding, repeat this procedure (choosing the next disk to be replaced).
