디스크가 H/W mirror 방식으로 구성되어 있는 경우 확인 방법.

 

SAS 디스크 일 경우 SAS controller 의 device name을 확인한다.

# ioscan -fn | grep sas
escsi_ctlr   0  0/4/1/0         sasd           CLAIMED     INTERFACE    HP  PCI/PCI-X SAS MPT Adapter
                               /dev/sasd0
ext_bus      3  0/4/1/0.0.0     sasd_vbus      CLAIMED     INTERFACE    SAS Device Interface

 

장치명이 /dev/sasd0 인 것을 확인.

 

 

# sasmgr get_info -D /dev/sasd0 -q raid
