Como posso descobrir se meu servidor tem algum tipo de IPMI?

Question

Eu nunca vi um servidor Linux que eu admin. Como posso saber se tem algum tipo de IPMI instalado?

Eu tentei responder minha própria pergunta instalando o ipmitool:

Setting up ipmitool (1.8.9-2) ...
Starting IPMI event daemon ipmievdipmievd: using pidfile /var/run/ipmievd.pid0
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such  file or directory
Unable to open interface
failed!
invoke-rc.d: initscript ipmievd, action "start" failed.

foi a resposta. Posso descobrir o que o ISP usa para controlar remotamente o servidor ou como o ISP provavelmente o conectou ao painel HTML de gerenciamento remoto?

    

Answer 1

Se for o Red Hat, basta fazer rpm -qa|grep ipmi . O OpenIPMI seria a instalação mais provável, ou uma das proprietárias (como o hpIPMI). Deve haver um comando equivalente nos sistemas .deb e Solaris também.

    

Answer 2

De seção do FAQ do FreeIPMI : 7. Meu sistema suporta o IPMI? .

Does my system support IPMI?

Unfortunately, there are no universally defined mechanisms for determining if a system supports IPMI via Inband communication. Assuming IPMI is set up correctly for over LAN communication, a fairly reliable mechanism exists out-of-band. Here are some suggestions.

1. FreeIPMI’s ipmi-locate can be used to determine if IPMI can be found on your system. Users are cautioned though, the failure to discover IPMI via ipmi-locate is not sufficient to disprove that IPMI exists on your system. Your system may not publish such information or may expect clients to communicate at default locations.

2. dmidecode may be similarly used to probe for devices that support IPMI on your system. You may grep for IPMI or specify the IPMI DMI type on the command line.

   # > dmidecode --type 38
   # dmidecode 2.10 SMBIOS 2.5 present.
   
   Handle 0x0049, DMI type 38, 18 bytes IPMI Device Information
           Interface Type: KCS (Keyboard Control Style)
           Specification Version: 2.0
           I2C Slave Address: 0x10
           NV Storage Device: Not Present
           Base Address: 0x0000000000000CA2 (I/O)
           Register Spacing: Successive Byte Boundaries
   

3. FreeIPMI’s ipmi-ping can be used to see if a machine has an IPMI service at a specific host/IP address. For more wide scale IPMI discovery, the ipmi-detectd daemon and ipmi-detect tool can be used.

Again, the failure to find an IPMI supported device is not sufficient to show lack of IPMI support.

Ultimately, some amount of information from product documents or trial and error may be necessary to determine if IPMI is supported on your system.
