This directory contains user space tools required by the ipr device driver.
|
|
To install them, type 'make' and then 'make install'. You will need pciutils-devel,
|
|
ncurses, ncurses-devel, and sysfsutils packages installed to perform the 'make'.
|
|
|
|
iprdump - A user program meant to be run in the background to gather debug
|
|
information should an IOA failure occur. Ideally, this program should be
|
|
started during boot time after file systems are loaded when the ipr
|
|
SCSI driver is used.
|
|
|
|
iprupdate - IOA/disk unit microcode update utility
|
|
This tool requires no arguments and should be run after each time the device driver
|
|
is loaded. It will query each adapter/disk unit for the microcode version and update
|
|
adapters/disk units that are not currently at the minimum supported levels.
|
|
|
|
iprconfig - IOA Configuration and Recovery tool
|
|
This is an ncurses based utility used to configure ipr adapters and devices.
|
|
The basic functions of this tool are:
|
|
|
|
CONFIGURATION
|
|
1. Display disk hardware status. This can be used to display all SCSI disks attached
|
|
to your system. Using this option it is possible to obtain the physical location
|
|
of each device on the system.
|
|
2. Work with SCSI Bus Configuration. This allows flexibility in setting some
|
|
SCSI Bus parameters such is Max Bus Throughput and host SCSI ID.
|
|
3. Work with Driver Configuration. Currently allows adjustment to the devices drivers
|
|
log level.
|
|
|
|
RAID
|
|
4. Delete a disk array. Allows you to delete existing arrays. Data stored
|
|
on the devices will not be preserved after issuing this command.
|
|
5. Create a disk array. Used to create a disk array.
|
|
6. Add a device to a disk array. This option allows devices of similar capacity
|
|
to be included into an existing disk array.
|
|
7. Configure a hot spare device. Configure a disk to become a hot spare, capable
|
|
of being used by the adapter to automatically replace a failed device
|
|
8. Format Device for advanced function/Format Device for JBOD (Just a Bunch Of DASD) function.
|
|
Disk devices can either be formatted to 512 bytes/sector or 522 bytes/sector. Devices must
|
|
be formatted to 522 bytes/sector, or advanced function format, in order to be used in
|
|
a disk array or as a hot spare. Devices not in a disk array can be formatted to
|
|
512 bytes/sector so they can be used directly by the operating system.
|
|
|
|
|
|
RECOVERY
|
|
9. Rebuild disk unit data. This option is generally used following concurrent
|
|
maintenance. Select this option after a failing array member device has been replaced to
|
|
reconstruct device as an active array member.
|
|
10. Device concurrent maintenance. This can be used to concurrently add or replace disk
|
|
units from a running system.
|
|
11. Reclaim IOA cache storage. This is to be used by IBM hardware service personnel only.
|
|
Use of this function is potentially dangerous and may delete data from the non-volatile
|
|
write cache on the adapter.
|
|
12. Initialize and format disk unit. This allows you to issue an actual SCSI format command
|
|
to SCSI disks. Proceed with caution when using this option.
|
|
13. Work with Resources Containing Cache Battery Packs. A set of displays are used to view
|
|
the current status of the Cache Battery on resources containing battery packs and allow
|
|
maintanence actions to be performed against those resources when necessary.
|
|
14. Analyze Log. This allows you to view the error messages logged by the ipr device driver.
