Attention: File System Risk Statement; Confirm How You Got To This Power 775 De Fan Service Procedure - IBM Power 775 Manual

2.2 ATTENTION: File System Risk Statement

The Global Parallel File System (GPFS) implementation of software RAID stripes data across all the Disk Enclosures in the
cluster. If a single Disk Enclosure is powered off while GPFS is active, the file system will go into panic and become
unavailable.
This service procedure requires powering off a Disk Enclosure and because of this requires interaction with GPFS in order
to limit impact to performance.
