Certify Media

This task allows the selection of diskette or hardfiles to be cer

Hardfiles can be connected either to a SCSI adapter (non-RAID) or RAID adapter. The usage and criteria for a hardfile connected t adapter are different from those for a hardfile connected to a adapter.

ŸCertify Diskette

This selection provides a way to verify the data written on a service aid is selected, a menu asks you to select the type

verified.	The program	then reads all of the	ID and	data field
time and	displays the	total number of bad	sectors	found.

ŸCertify Hardfile Attached to a Non-RAID SCSI Adapter

This selection reads all of the ID and data fields. It chec counts all errors encountered. If the unrecovered data errors threshold value, the hardfile needs to be formatted and certif data errors, recovered and unrecovered equipment errors exceed values, the disk needs to be replaced.

This task may be run directly from the AIX command line. The f statement describes the syntax of the command:

Usage:

diag -c -d <deviceName> -T "certify"

ŸCertify Hardfile attached to a PCI SCSI RAID Adapter

This selection is used to certify physical disks attached to a adapter. Certify reads the entire disk and checks for recovere

unrecovered errors and reassigned errors. If these errors exc

values, the user is	prompted to	replace	the physical disk.
This task may be run directly from the			AIX command line. The fo
statement describes	the syntax	of the	command:

Usage:

diag -c -d < RAID adapterName > -T "certify {-l < chID > -A}"

Flag	Description
-I	Physical Disk channel/ID (example: 27)
-A	All disks.
