问题描述

LIF为admin UP 、但operationally down 处于扩展状态-"FDISC error - ID could not be acquired for this virtual port"
托管LIF的适配器处于联机状态。
在EMS 日志中为相关适配器报告以下事件：

[DC_FAS8700-01: fct_tpd_thread_1: fcp.io.status:debug]: STIO Adapter:1b, found hung cmd:0xfffff80ec6ad47e0(state=10, flags=0x2,ctio_sent=2/2,RecvExAddr=0x1911, OX_ID=0xa18, RX_ID=0xffff,SID=0x247xx, Cmd[28],req_q_free:0[DC_FAS8700-01: fct_tpd_thread_1: scsitarget.fct.reset:notice]: Resetting Fibre Channel target adapter 1b.

如果此端口已连接到Brocade交换机、请检查每端口NPIV登录限制(请参见"portcfgshow "中的"NPIV PP Limit ")是否设置为零或值太低、无法允许所有LIF登录。
如果需要修改此值，我们可以Brocade使用"portCfgDefault ”(注- 此操作将覆盖所有端口设置)。
或者、我们也可以使用专门设置登录限制 "portcfgnpivport --setloginlimit"
- 对于portcfgshow 中的相关端口，NPIV限制设置为126：
