Symptoms

环境：
EMC 硬件：Connectrix ED-DCX-B
EMC 硬件：Connectrix ED-DCX-4S
EMC 硬件：Connectrix ED-8510-4B
EMC 硬件：Connectrix ED-8510-8B
软件：Fabric OS 7.3.1
 
问题：
1.每分钟发生一次 errdump 中的 HA 不同步消息： 
2017/02/17-07:49:24, [MAPS-1020], 32312, SLOT 6 | FID 128, WARNING, DCX, Switch wide status has changed from HEALTHY to MARGINAL..
2017/02/17-07:50:24, [MAPS-1020], 32313, SLOT 6 | FID 128, WARNING, DCX, Switch wide status has changed from MARGINAL to HEALTHY.
2017/02/17-07:51:24, [MAPS-1020], 32314, SLOT 6 | FID 128, WARNING, DCX, Switch wide status has changed from HEALTHY to MARGINAL.
2017/02/17-07:52:24, [MAPS-1020], 32315, SLOT 6 | FID 128, WARNING, DCX, Switch wide status has changed from MARGINAL to HEALTHY.

映射守护程序 （MDD） 在一段时间后终止： 
[KSWD-1002], 51122/32327, SLOT 6 | FFDC | CHASSIS, WARNING, DCX, Detected termination of process mdd:2209., hasm_swd.c, line: 191, comp:insmod, ltime:
[FSSM-1003], 51123/32328, SLOT 7 | CHASSIS, WARNING, DCX, HA State out of sync., OID:0x003e0007, hasm_sgi.c, line: 2139, comp:hamd, ltime:
[RAS-5001], 51124/0, SLOT 6 | CHASSIS, INFO, DCX, Message KSWD-1002 caused FFDC event, ffdcd.c, line: 1030, comp:raslogd, ltime:
[RAS-1001], 51125/32329, SLOT 6 | CHASSIS, INFO, DCX, First failure data capture (FFDC) event occurred., ffdcd.c, line: 1031, comp:raslogd, ltime:
 
2.另一个问题是，Maps 守护程序 （MDD） 在活动 CP 上死机并重新启动。因此，控制器失去 HA SYNC 状态。

Cause

由于代码中存在空指针引用，MAPS 守护程序已终止。MAPS 守护程序死机并且未在活动 CP 上重新启动，因此控制器会丢失 HA SYNC。当备用 CP 频繁处于和退出故障状态，并且即使在更换备用 CP 后也无法恢复 HA 时，就会发生这种情况。

Resolution

解决方案：
升级到 Fabric OS 版本 7.4.1e、7.4.2、8.0.2 或 8.1.0。

解决办法：
对于问题 2，请计划维护窗口并重新启动活动 CP，这会造成中断，因为 CP 不同步。
