Hardfile Attached To Pci Scsi Raid Adapter; Optical Media; Diskette Format; Gather System Information - IBM pSeries 690 User Manual

7. If the bad block list is the same, continue running the service aid to overwrite the disk with the
chosen pattern(s).
This task can be run directly from the AIX command line. See the command syntax: diag -c -d
deviceName -T "format [-s* fmtcert | erase -a {read | write}] [-F]"
Flag Description
fmtcert Formats and certifies the disk.
* Available in no-console mode only.
-F Force the disk erasure even if all blocks cannot be erased due to errors accessing grown
defect map.
Note: The Erase Disk option in command line mode uses default values. To selectively read or write, use
the diag command in console mode.

Hardfile Attached to PCI SCSI RAID Adapter

This function formats the physical disks attached to a PCI SCSI RAID adapter. This task can be run
directly from the AIX command line. See the following command syntax: diag -c -d RAIDadapterName -T
"format {-l chId | -A }"
Flag Description
-l Physical disk channel/ID (An example of a physical disk channel/ID is 27, where the channel is 2
and the ID is 7.)
-A All disks

Optical Media

Use the following functions to check and verify optical media:
v Optical Media Initialize
Formats the media without certifying. This function does not reassign the defective blocks or erase the
data on the media. This option provides a quick way of formatting the media and cleaning the disk.
Note: It takes approximately one minute to format the media.
v Optical Media Format and Certify
Formats and certifies the media. This function reassigns the defective blocks and erases all data on the
media.
This task can be run directly from the AIX command line. See the following command syntax: diag -c -d
deviceName -T "format [-s {initialize | fmtcert} ]"
Option Description
initialize Formats media without certifying
fmtcert Formats and certifies the media

Diskette Format

This selection formats a diskette by writing patterns to it.

Gather System Information

This service aid uses the AIX snap command to collect configuration information on networks, file systems,
security, the kernel, the ODM, and other system components. You can also collect SSA adapter and disk
drive configuration data, or AIX trace information for software debugging.
The output of the SNAP service aid can be used by field service personnel, or it can be put on removable
media and transferred to remote locations for more extensive analysis.
