Analyze Adapter Internal Log
The PCI RAID adapter has an internal log that logs information about the adapter and
the disk drives attached to the adapter. Whenever data is logged in the internal log, the
device driver copies the entries to the AIX system error log and clears the internal log.
The Analyze Adapter Internal Log service aid analyzes these entries in the AIX system
error log. The service aid displays the errors and the associated service actions. Entries
that do not require any service actions are ignored.
Backup and Restore Media
This service aid allows verification of backup media and devices. It presents a menu of
tape and diskette devices available for testing and prompts for selecting the desired
device. It then presents a menu of available backup formats and prompts for selecting
the desired format. The supported formats are tar, backup, and cpio. After the device
and format are selected, the service aid backs up a known file to the selected device,
restores that file to /tmp, and compares the original file to the restored file. The restored
file remains in /tmp to allow for visual comparison. All errors are reported.
Certify Media
This task allows the selection of diskette or hard files to be certified.
Hard files can be connected either to a SCSI adapter (non-RAID) or a PCI SCSI RAID
adapter. The usage and criteria for a hard file connected to a non-RAID SCSI adapter
are different from those for a hard file connected to a PCI SCSI RAID adapter.
v
Certify Diskette
This selection enables you to verify the data written on a diskette. When you select
this service aid, a menu asks you to select the type of diskette being verified. The
program then reads all of the ID and data fields on the diskette one time and
displays the total number of bad sectors found.
v
Certify Hardfile Attached to a Non-RAID SCSI Adapter
This selection reads all of the ID and data fields. It checks for bad data and counts
all errors encountered. If the unrecovered data errors exceed the threshold value, the
hard file needs to be formatted and certified. If the recovered data errors, as well as
recovered and unrecovered equipment errors exceed the threshold values, the disk
needs to be replaced.
This task can be run directly from the AIX command line. The command syntax is as
follows:
diag -c -d
deviceName
-T "certify"
v
Certify Hardfile attached to a PCI SCSI RAID Adapter
This selection is used to certify physical disks attached to a PCI SCSI RAID adapter.
Certify reads the entire disk and checks for recovered errors, unrecovered errors,
and reassigned errors. If these errors exceed the threshold values, the user is
prompted to replace the physical disk.
This task can be run directly from the AIX command line. See the following command
syntax:
diag -c -d
RAID adapterName
-T "certify {-l
chID |
-A}"
