System Administration | showcomponent(1m) |
| showcomponent - display the blacklist status
for a component |
SYNOPSIS
| showcomponent [-a|-d domain_indicator] [-v] [location ...] |
|
showcomponent(1M) indicates whether the specified component is listed in the platform, domain, or ASR blacklist file.
If neither the -a nor the -d option is specified, showcomponent displays the platform blacklist. If no location is specified, showcomponent displays all components in the specified blacklist.
The blacklist is an internal file that lists components that POST cannot use at boot time. POST reads the blacklist file(s) before preparing the system for booting, and passes along to OpenBoot PROM a list of only those components that have been successfully tested; those on the blacklist are excluded.
SMS supports three blacklists: one for domain boards, one for platform boards, and the internal automatic system recovery (ASR) blacklist.
For more information on the use and editing of platform and domain blacklists refer to Chapter 6, "Domain Control," in the System Management Services (SMS) 1.4 Administrator Guide.

|
The following options are supported:
- -a
- Specifies the ASR blacklist.
- -d domain_indicator
- Specifies the domain using one of the following:
domain_id - ID for a domain. Valid domain_ids are A-R and are not case sensitive.
domain_tag - Name assigned to a domain using addtag(1M).
- -h
- Help. Displays usage descriptions. Note Use alone. Any option specified in addition to -h is ignored.
- -v
- Verbose. Displays all available command information.

The following operands are supported:
-
location
- List of component locations, separated by forward slashes and comprised of:
board_loc/proc/bank/logical_bank
board_loc/proc/bank/all_dimms_on_that_bank
board_loc/proc/all_banks_on_that_proc
board_loc/all_banks_on_that_board
board_loc/proc
board_loc
board_loc/procs
board_loc/cassette
board_loc/bus
board_loc/paroli_link
-
- Multiple location arguments are permitted, separated by a space.
The location forms are optional and are used to specify particular components on boards in specific locations.
For example, the location SB5/P0/B1/L1 indicates
Logical Bank 1 of Bank 1 on Processor 0 at SB5.
The SB0/PP1 location indicates Processor Pair 1 at SB0.
The CS0/ABUS1 location indicates address bus 1 at CS0.
The following board_loc forms are accepted:
Sun Fire 15K, Sun Fire 12K
SB(0...17), SB(0...8)
IO(0...17), IO(0...8)
CS(0|1), CS(0|1)
EX(0...17), EX(0...8)
-
-
-
- Processor locations indicate single processors or processor pairs.
There are four possible processors on a CPU/memory board. Processor pairs on that board are procs 0 and 1, and procs 2 and 3.
The MaxCPU has two processors: procs 0 and 1, and only one proc pair (PP0). Using PP1 for this board causes showcomponent to exit and display an error message.
The following proc forms are accepted:
P(0...3) PP(0|1)
The following bank forms are accepted:
B(0|1)
The following logical_bank forms are accepted:
L(0|1)
The following all_dimms_on_that_bank forms are accepted:
D
The following all_banks_on_that_proc forms are accepted:
B
The following all_banks_on_that_board forms are accepted:
B
The following paroli_link forms are accepted:
PAR(0|1)
-
- The hsPCI assemblies contain hot-swappable cassettes.
The following hsPCI forms are accepted:
C(3|5)V(0|1)
-
- The hsPCI+ assemblies contain hot-swappable cassettes.
The following hsPCI+ forms are accepted:
C3V(0|1|2) and C5V0
-
- There are three bus locations: address, data, and response.
The following bus forms are accepted:
ABUS|DBUS|RBUS (0|1)
