[Linux] PCI 정보 확인

출처 : 불량펭귄(http://blog.helperchoi.com/95)

 

Linux System에서는 아래와 같이 dmidecode 및 lspci 명령을 통해 PCI Slot 정보를 확인 가능하다.

 

1. 전체 PCI Slot 수와 Slot Type 확인

 

[root@TestDB01 ~]# dmidecode -t slot | grep Type | wc -l 16 [root@TestDB01 ~]# [root@TestDB01 ~]# dmidecode -t slot | grep Type            Type: x4 PCI Express Gen 2 x8            Type: x4 PCI Express Gen 2 x8            Type: x8 PCI Express Gen 2 x16            Type: x4 PCI Express Gen 2 x8            Type: x8 PCI Express Gen 2 x16            Type: x4 PCI Express x8            Type: x8 PCI Express Gen 2 x16            Type: x8 PCI Express Gen 2 x16            Type: x4 PCI Express Gen 2 x8            Type: x8 PCI Express Gen 2 x16            Type: x8 PCI Express Gen 2 x16            Type: x8 PCI Express Gen 2 x16            Type: x8 PCI Express Gen 2 x16            Type: x4 PCI Express Gen 2 x8            Type: x8 PCI Express Gen 2 x16            Type: x8 PCI Express Gen 2 x16 [root@TestDB01 ~]#

 

 

 

2. 가용 가능 여분 PCI Slot 확인

 

[root@TestDB01 ~]# dmidecode -t slot | grep -i "available" | wc -l 3 [root@TestDB01 ~]# [root@TestDB01 ~]# dmidecode -t slot | grep -i "available" -B2 -A5  Designation: PCI-E Slot 14  Type: x4 PCI Express Gen 2 x8  Current Usage: Available  Length: Short  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:a7:00.0 --  Designation: PCI-E Slot 15  Type: x8 PCI Express Gen 2 x16  Current Usage: Available  Length: Short  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:aa:00.0 --  Designation: PCI-E Slot 16  Type: x8 PCI Express Gen 2 x16  Current Usage: Available  Length: Short  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:ad:00.0 [root@TestDB01 ~]# [root@TestDB01 ~]#

 

 

 

3. 현재 사용중인 PCI Slot과 해당 BUS 정보 확인

 

[root@TestDB01 ~]# [root@TestDB01 ~]# dmidecode -t slot | grep -i "in use" -B2 -A5  Designation: PCI-E Slot 7  Type: x4 PCI Express Gen 2 x8  Current Usage: In Use  Length: Long  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:05:00.0 --  Designation: PCI-E Slot 8  Type: x4 PCI Express Gen 2 x8  Current Usage: In Use  Length: Long  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:08:00.0 --  Designation: PCI-E Slot 9  Type: x8 PCI Express Gen 2 x16  Current Usage: In Use  Length: Long  Characteristics:   3.3 V is provided   PME signal is supported  Bus Address: 0000:0b:00.0 -- . . . 생략

 

 

 

4. 현재 PCI Slot에 장착된 HBA Card(FC-Card) 확인
