The system software recognizes the disk drive module by a machine-readable number
that is written on the electronics card of the disk drive module. This number is shown
also on the label at the front of a disk drive module. The service aids show the number
as the last eight digits of the IEEE 16-digit SSA unique identifier (UID).
Service actions are always related to physical disk drives. For this reason, errors that
occur on SSA disk drives are always logged against the physical disk drive (pdisk).
If a disk drive that has been formatted on a machine of a particular type (for example, a
Personal System/2) is later installed into a using system that is of a different type (for
example, an RS/6000), that disk drive is configured only as a pdisk during the
configuration of the using system.
Limitations:
1. Various types of 10 000 rpm disk drives are available. Their actual speeds are in the
range 9 991 through 10 091 rpm.
2. If the customer configures an
Eserver
pSeries volume group on a 15+P RAID-5
array that is using 72.8 GB disk drives, the customer must set the form factor to 2
or above. This action allows the number of physical partitions to be set inside the
AIX limit. If the customer does not do this action, the volume group fails to
configure.
3. A pSeries RAID-0 volume group that uses 72.8 GB disk drives can contain no more
than 15 of those disk drives.
4. On all disk drives, the adapter reserves 65 536 bytes for its own use.
5. Disk drive modules for 7133 Models 010, 020, 500, and 600 cannot be installed in
7133 Models D40 and T40. Also, disk drive modules for the 7133 Models D40 and
T40 cannot be installed in 7133 Models 010, 020, 500, and 600.
Software and Microcode Errors
Some failures might be caused by software errors or by microcode errors. If you think
you have a software or microcode error:
1. Ensure that your system software, controller microcode, and disk drive microcode
are all at the latest levels. Information about the latest levels of software and
microcode is given on the web support page (see “Web Support Pages” on
page 254).
2. Make a note of all failure indicators: for example, the contents of error logs, or
physical symptoms.
3. For AIX Versions 4.2 and above, run the snap -b command to collect system
configuration data, and to dump data.
For AIX versions below 4.2, go to the using-system service aids and select
Display
Vital Product Data
to display the VPD of the failing system. Make a note of the
VPD for all the SSA adapters and disk drives.
4. Report the problem to your support center. The center can tell you whether you
have a known problem, and can, if necessary, provide you with a correction for the
software or microcode.
