Physical View )

Common Attributes: (Common to all Disk types and all usage classes) |
Usage: The usage
of an SSA resource determines how you can use the resource. All possible
usage classes are explained in the Resource List
help. Status: The status of this disk resource.
Size: The capacity of the disk - in Giga-Bytes.
Vendor ID: The disk drive manufacturer.
Product ID: The disk drive type. The first four characters detail the type of microcode which is required by this disk. See SSA Tool Help for more information.
Model Number: The disk drive model. (Usually the same as the second part of the Product ID.
ROS Revision: The level of ROS microcode. (IBM disks only)
RAM Revision: The level of RAM microcode. (IBM disks only)
Note: | Combining the ROS and RAM fields will give you the current microcode level on this disk. This is used by the checklevel function, along with the Product ID to check if you have the latest drive microcode on this disk. |
Note: | Some newer disk drive combine these two fields as the level. |
Manufacture Date: The date the disk was manufactured. (yy/mm/dd)
Servo Microcode: The level of servo microcode.
HDE Serial Number: The Head Disk Enclosure serial number of this disk.
Additional Fast Write Attributes:

See the Fast Write Attributes section in the array view help.
Additional 'System (PC)' Attributes:
|
![]() |
'System PC' disks have the following attributes on a PC Server in addition to the common attributes outlined above.
Access: When running in Cluster Mode
arrays and disks can be made private to one adapter. That is, only one
adapter can access the resource. Access can be set only when the resource
is in the usage class 'System (PC)'.
Cluster Mode Only. The access can be set to three types:
Resource Number: The resource number as assigned when the resource was 'Attached' to the system. This dictates the order in which the System (PC) resources are presented to the operating system. See the description and notes above.
Additional 'System (AIX)' Attributes:
|
![]() |
'System AIX' disks have the following attributes on AIX in addition to the common attributes outlined above.
Disk: The physical name and the logical name
of the resource. Location: The physical location of the resource.
Additional Array Member Attribute:
Array member disks have the following attributes in
addition to the common attributes outlined
above.
IBM Advanced SerialRAID/X Adapter
Only
Pool Id: The
Hot-spare pool that this resource is a member
of. Disk:2
The name of the physical array members. Actions:
This action checks if the level of disk microcode on this disk
is the latest. This action requires the machine running the browser to be
connected to the Internet This action updates the current page. This action starts flashing the indicator light on the disk.
A message will be displayed in the Information Area
indicating the resource is flashing. This message
will appear only once. You must remember to Flash Off the
resource, or the light will continue to flash. To clear all indicators,
use the Flash All Off button on the
Adapter View to Flash Off the indicator
lights on all disks attached to the selected adapter. This action stops the indicator light flashing on the disk. This action starts the disk drive diagnostic funtion. This action will take you to the
Create Fast Write attributes page. When complete,
the disk will use the Fast Write Cache for data writes.
Fast Write Adapters Only. This action will take you to the
Modify Fast Write attributes page where you can
modify some of the current disk attributes.
Fast Write Adapters Only. This action will stop the disk from using the Fast Write Cache
for data writes.
Fast Write Adapters Only. This action changes the use of a disk from 'System (AIX)' to 'Free'.
'System (AIX)' or 'System (PC)' Resources Only This action changes the use of a disk from
'Free' to
'System PC'. The disk will then be available to the operating system. This action links to the Attach page, where a resource number is chosen. This number dictates th order in which resources are presented to the operating system. This action changes the use of a disk from 'System (PC)' to
Free. The resource will no longer be available to the operating
system. 'System (PC)' Resources Only This action sets the resource access to public.
'System (PC)' Resources and
Cluster Mode Only This action sets the resource access to private.
'System (PC)' Resources and
Cluster Mode Only This action sets the resource access to No Access.
'System (PC)' Resources and
Cluster Mode Only This action allows you to Exchange an array
member for another disk. This action will appear if you have
accessed the Disk view from the relevant
Array view. Array members Only
Additional Physical View Actions:
When a Disk View is selected from the
Physical View, rather than the Logical View, the following additional actions will
be available.
This action performs a low level format operation on the disk.
If successful, the disk will be a member of the usage class
'System (AIX)'.
Low level formatting of a resource will result in all data, including SSA
configuration data, being destroyed. Ensure this is what you want to
do before proceeding. Format can only be performed when the relevant disk view
has been selected from the Physical View - Selecting a disk
from any other view will result in the Format option not being
available. This action starts the certification operation on the disk. This
performs read/write actions to all data areas on the disk.
Certify can only be performed when the relevant disk view
has been selected from the Physical View - Selecting a disk
from any other view will result in the Certify option not being
available. This action should be used when removing any disks from an active SSA
loop. It will attempt to stop the disk motor, prevent link errors, and start
the indicator light. See the Physical View help for a more
information relating to Service Mode.
Only 'System (AIX)' on PC Server systems, 'System (PC)' on AIX systems, 'Free', or 'Rejected' disks can be set in Service Mode. Only array members of
degraded arrays can be set in
Service Mode. Fast Write resources cannot
be put in Service Mode no matter what their usage.
Service Mode can only be set when the relevant disk view
has been selected from the Physical View - Selecting a disk
from any other view will result in the Set Service Mode option
being unavailable. Related Information
