我們已經花費EMC存儲上的現有LUN大小,現在我想重新掃描主機端,但我不知道如何找出該特定LUN的SCSI ID。我是新來存儲。這是我在做什麼,但不知道它是否是一個正確的方式或不在Linux上重新掃描LUN
Pseudo name=emcpowerj
CLARiiON ID=APM00112500570 [Oracle_Cluster]
Logical device ID=200601602E002900B6BCA114C9F8E011 [LUN01]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0;
Owner: default=SP A, current=SP A Array failover mode: 1
==============================================================================
--------------- Host --------------- - Stor - -- I/O Path -- -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
2 qla2xxx sdaj SP A1 active alive 0 1
2 qla2xxx sdaw SP B1 active alive 0 4
1 qla2xxx sdj SP A0 active alive 0 1
1 qla2xxx sdw SP B0 active alive 0 4
我在這裏sdX的設備上運行find命令找出SCSI ID來我可以做echo 1 > /sys/bus/scsi/drivers/X:X:X:X/rescan
做重新掃描LUN
$ find /sys/devices -name "*block*" | grep -e "sdaj" -e "sdaw" -e "sdj" -e "sdw"
/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.1/host2/rport-2:0-1/target2:0:1/**2:0:1:8**/block:sdaw
/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.1/host2/rport-2:0-0/target2:0:0/**2:0:0:8**/block:sdaj
/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.0/host1/rport-1:0-1/target1:0:1/**1:0:1:8**/block:sdw
/sys/devices/pci0000:00/0000:00:09.0/0000:05:00.0/host1/rport-1:0-0/target1:0:0/**1:0:0:8**/block:sdj
或存在替代或其他方式來掃描LUN?
