Error numbers specific to GPFS application calls when disk failure occurs

There are certain error numbers associated with GPFS application calls when disk failure occurs.

When a disk failure has occurred, GPFS may report these error numbers in the operating system error log, or return them to an application:
EOFFLINE = 208, Operation failed because a disk is offline
This error is most commonly returned when an attempt to open a disk fails. Since GPFS will attempt to continue operation with failed disks, this will be returned when the disk is first needed to complete a command or application request. If this return code occurs, check your disk for stopped states, and check to determine if the network path exists.

To repair the disks, see your disk vendor problem determination guide. Follow the problem determination and repair actions specified.

ENO_MGR = 212, The current file system manager failed and no new manager could be appointed.
This error usually occurs when a large number of disks are unavailable or when there has been a major network failure. Run the mmlsdisk command to determine whether disks have failed. If disks have failed, check the operating system error log on all nodes for indications of errors. Take corrective action by issuing the mmchdisk command.
