Detailed Description
SSA error logs are grouped into types of errors. Each type of error is assigned to an
Error Label and an Error ID. The Error Label specifies the text that appears when the
error log is displayed. It also specifies the priority that is applied to each error type
when the cause of a problem is determined. The Error ID is a numeric identifier for the
Error Label. Table 2 shows the error labels that SSA subsystems use.
Table 2. Error Labels
Error Label Error ID Error Description
DISK_ERR1 21F54B38 An unrecovered media error has been detected. The problem will
be solved automatically when data is next written to the failing
block. If you are using RAID-5, no application has failed. If you
are not using RAID-5, an application might have had a media
error. Run error log analysis to determine whether the disk drive
has become unreliable and should be exchanged for a new one.
DISK_ERR4 1581762B A recovered media error has been detected. An occasional
recovered media error is not serious. Multiple media errors per
day on one disk drive, however, might indicate that the disk drive
is failing. Run error log analysis to determine whether the disk
drive should be exchanged for a new one.
SSA_ARRAY_ERROR B4C00618 A RAID array failure has been detected, and the array is not fully
operational. Usually, the data on the array is safe, but ensure
that you follow the service procedures exactly so that you do not
lose any data.
SSA_CACHE_ERROR BC31DEA7 These errors indicate that the fast-write cache has detected a
problem. Usually, the problem has been caused by user or
service actions, such as moving a Fast-Write Cache Option card
from one adapter to another, or moving a disk drive between
adapters before the data in the cache card has been
synchronized with the data on the disk drive. Take care when
moving cache cards, or adapters that contain cache cards,
because they might contain data that needs to be synchronized.
Always follow the service procedures for the SRN carefully to
ensure that you do not lose any data.
SSA_CACHE_BATTERY 26CA120B This error recommends that the battery of the Fast-Write Cache
Option card be exchanged for a new one.
SSA_DEGRADED_ERROR 3DB7729E An error or condition has occurred that might cause some of the
SSA functions to be unavailable or to be working with reduced
performance.
SSA_DETECTED_ERROR EC9903DF Errors of this type are logged by the adapter when a device
failure has been reported via SSA asynchronous messages.
Because the system name of the device, or devices, that are
sending these messages is not known, the error is logged
against the adapter. The SRN indicates the service procedures
that must be performed.
