演示中心ESX主机添加网卡和内存

今天我们的两台ESX服务器都作了升级，现在的内存都是3个G了。但网卡ESX 3不认。

使用esxcfg-nics –l看不到新的网卡，然后用lspci –v, 显示如下:

03:01.0 Ethernet controller: D-Link System Inc: Unknown device 4b01 (rev 11)

        Subsystem: D-Link System Inc: Unknown device 4b01

        Flags: bus master, 66Mhz, medium devsel, latency 32, IRQ 20

        Memory at f1040000 (32-bit, non-prefetchable) [size=16K]

        I/O ports at d000 [size=256]

        Expansion ROM at [disabled] [size=128K]

        Capabilities: [48] Power Management version 2

        Capabilities: [50] Vital Product Data

 

显示不认识D-Link的NIC。查了一下vi3_io_guide.pdf, 原来ESX3只支持Intel和Broadcom的NIC. 这倒也见简单，就好像FC HBA只支持Qlogic和Emulex，但价格贵了许多倍，需要1000多元，而D-Link的才150元。

 

加完内存后，可以用以下的方法确认：

1)       从Virtual Center中，这个最直观了

2)       从Service Console中，运行esxtop, 然后按m显示memory信息

  2:18:59am  up  2:15, 36 worlds; MEM overcommit average:

PMEM   (MB):  3070   total:   272     cos,   119    vmk, ee

VMKMEM (MB):  2740 managed:   164 minfree,   168   rsvd, ate

COSMEM (MB):     6    free:   541  swap_t,   541 swap_f:

3)       从Service Console中，cat /proc/vmware/mem

TOTALS                  0/0      685352/2677

不过以上显示很难看懂，还是用cat /proc/meminfo看看：

        total:    used:    free:  shared: buffers:  cached:

4)       最详细的就是用esxcfg-info|grep –I mem, 以下为部分输出

\==+MemoryInfoImpl :

   |----System Mem............................................30715

   |----Physical Mem..........................................3220045824

8月21日下午，网卡终于成功识别，以下是看到的信息：

[root@BI-ESX2 root]# esxcfg-nics -l

那个显示Down的表示是因我没插网线
