Oracle® ZFS Storage Appliance Customer Service Manual
For ZS3-x, 7x20 Controllers, and DE2-24, Sun Disk Shelves
Remove all plastic, vinyl, and foam material from the work area.
Wear an antistatic wrist strap at all times when handling any CRU.
Before handling any CRU, discharge any static electricity by touching a grounded surface.
Do not remove a CRU from its antistatic protective bag until you are ready to install it.
After removing a CRU from the chassis, immediately place it in an antistatic bag or antistatic packaging.
Handle any card that is part of a CRU by its edges only and avoid touching the components or circuitry.
Do not slide a CRU over any surface.
Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.
Most disk shelf components are hot-swappable; you do not need to remove power when replacing them. Do not remove a component if you do not have an immediate replacement. The disk shelf must not be operated without all components in place.
Powering off or removing all SAS chains from a disk shelf will trigger a kernel panic on the controller(s) to prevent data loss, unless the shelf is part of an NSPF (no single point of failure) data pool. To avoid this, shut down the controller(s) before decommissioning the shelf. For details on NSPF profiles, see Storage Configuration Profile in Oracle ZFS Storage Appliance Administration Guide .
