I have been hunting for a system that has a Generic Device Locator
so I can see what the output of the rather obscure "ipmitool gendev list"
command would give (well, 26 hits on google counts as obscure in
my book ;))
First, a bug - the ipmitool man page doesn't list the option at
all. You can see it with ipmitool --help
# ipmitool 2>&1 | grep gen
gendev Read/Write Device associated with Generic Device
locators sdr
# ipmitool gendev
Rx gendev command: (null)
SDR Commands: list read write
list List All Generic Device Locators
read <sdr name> <file> Read to file eeprom specify by Generic
Device Locators
write <sdr name> <file> Write from file eeprom specify by Generic
Device Locators
The best explanation I could see was from the IPMI spec (page 564):
Intelligent Platform Management Interface Specification
43.7 SDR Type 10h - Generic Device Locator Record
This record is used to store the location and type information for
devices on the IPMB or management controller private busses that
are neither IPMI FRU devices nor IPMI management controllers. These
devices can either becommon non-intelligent I2C devices, special
management ASICs, or proprietary controllers.
(It has a nice table and more details about this as well - if you don't have
the doc memorized it's at
http://www.scribd.com/doc/58588834/643/SDR-Type-10h-Generic-Device-Locator-Record)
The source file "lib/ipmi_gendev.c" has some interesting comments
that appear to point to what it might output:
lprintf(LOG_ERR, "Generic device: %s", dev->id_string);
lprintf(LOG_ERR, "I2C Chnl: %x", channel);
lprintf(LOG_ERR, "I2C Bus : %x", i2cbus);
lprintf(LOG_ERR, "I2C Addr: %x", i2caddr);
lprintf(LOG_ERR, "Gen Device : %s", dev->id_string);
lprintf(LOG_ERR, "Access Addr: %x", dev->dev_access_addr);
lprintf(LOG_ERR, "Slave Addr : %x", dev->dev_slave_addr);
lprintf(LOG_ERR, "Channel Num: %x", dev->channel_num);
lprintf(LOG_ERR, "Lun : %x", dev->lun);
lprintf(LOG_ERR, "Bus : %x", dev->bus);
lprintf(LOG_ERR, "Addr Span : %x", dev->addr_span);
lprintf(LOG_ERR, "DevType : %x", dev->dev_type);
lprintf(LOG_ERR, "DevType Mod: %x", dev->dev_type_modifier);
But these are comments and I don't really want to know the guts of
ipmitool enough to follow it around (my own systems don't print
anything!) Does anyone have more information about this, or,
better still, a working example of a command, output, and how it
might be used?
Thanks!
