HACMP Method

사전 구성확인

# odmget HACMPcustom

HACMPcustom: 

name = "set_scsi_id" 

type = "event" 

description = "Set correct scsi id on EMC CLARiiON pseudo devices." 

value = "/etc/set_scsi_id'" 

relation = ""

Step 1) 기존 “set_scsi_id” 정보를 삭제

/usr/es/sbin/cluster/utilities/clrmcustom -t event -n 'set_scsi_id'

Step 2) 새로운 script(cfgscsi_id)를 HACMPcustom에 추가

# /usr/es/sbin/cluster/utilities/claddcustom -t event -n 'cfgscsi_id' -I 'Set correct scsi id on EMC CLARIION pseudo device.' -v '/usr/sbin/cfgscsi_id'

Step 3) odm에 제대로 인식이 되었는지 확인 

# odmget HACMPcustom

HACMPcustom:

name = "cfgscsi_id"

type = "event"

description = "Set correct scsi id on EMC CLARiiON pseudo devices."

value = "/usr/sbin/cfgscsi_id"

relation = ""

status = 0 

Step 4) hacmp node_up, node_down pre-event에 등록

#/usr/es/sbin/cluster/utilities/clchevent -O'node_up' -s'/usr/es/sbin/cluster/events/node_up' -b 'cfgscsi_id' -c '0'

#/usr/es/sbin/cluster/utilities/clchevent -O'node_down' -s'/usr/es/sbin/cluster/events/node_down' -b 'cfgscsi_id' -c '0' 

Step 5) hacmp node_up, node_down pre-event에 등록 확인

# odmget -q name=node_up HACMPevent

HACMPevent:

name = "node_up"

desc = "Script run when a node is attempting to join the cluster."

setno = 101

msgno = 7

catalog = "events.cat"

cmd = "/usr/es/sbin/cluster/events/node_up"

notify = ""

pre = "cfgscsi_id"

post = ""

recv = ""

count = 0

event_duration = 0

# odmget -q name=node_down HACMPevent

HACMPevent:

name = "node_down"

desc = "Script run when a node is attempting to leave the cluster."

setno = 101

msgno = 8

catalog = "events.cat"

cmd = "/usr/es/sbin/cluster/events/node_down"

notify = ""

pre = "cfgscsi_id"

post = ""

recv = ""

count = 0

event_duration = 0

Step 6) emcpowerreset 기존 정보 확인(아래 정보와 다른 경우 Step 7 실행)

# odmget HACMPdisktype

HACMPdisktype:

PdDvLn = "disk/pseudo/power"

ghostdisks = "SCSI3"

checkres = "SCSI_TUR"

breakres = "/usr/lpp/EMC/CLARiiON/bin/emcpowerreset"

parallel = "false"

makedev = "MKDEV"

reserved1 = ""

reserved2 = ""

reserved3 = ""

Step 7) Setup "emcpowerreset" for HACMP 5.2 Classic and ES (SMIT)

# /usr/sbin/cluster/utilities/clcustomdisk -c -tdisk/pseudo/power -Ndisk/pseudo/power -gSCSI3 -hSCSI_TUR -b/usr/lpp/EMC/CLARiiON/bin/emcpowerreset -ptrue -mMKDEV
