EXP24SX에서 SAS MODE변경 매뉴얼을 조금 정리해 봤습니다.
1. 기존 데이터에 대한 손실이 가능하기에 모든 데이터에 대한 백업은 당연하겠죠.
2. 파티션에 할당된 디스크를 포함한 EXP24SX는 MODE 변경이 지원되지 않습니다.
3. Planning
a. RPO MES recommended.
b.Expert storage configuration skills recommended.
c. SAS cabling configuration. Each mode setting for an enclosure has a specific set of valid I/O adapter and
4. 절차

c. Physically unplug all storage devices from the enclosure to be reconfigured.
d. Re-apply electrical power to the enclosure
e. Power on the partition containing the enclosure. For IBM i, IPL in attended (manual) mode only and

5. 재구성 수행 - AIX
/usr/lpp/diagnostics/bin/ses_mode
The syntax is: /usr/lpp/diagnostics/bin/ses_mode -d device [-z <n>]
-d device where device is the SAS disk enclosure that is zoned to share disks to different
partitions.
-z <n> set the zone mode to <n> (n is 1, 2 or 4)
6. 재구성 수행 - Linux
To check mode
iprconfig -c query_ses_mode sg#
To set mode
iprconfig -c set_ses_mode sg# <mode>
sg# is the sg device, such as sg5, and <mode> is the mode number, such as 2.
