Enable/Disable GTM pool member by java Icontrol

i suggest you use python sdk: f5-sdk

here  is the code to find which gtm pool member is be disabled:

from f5.bigip import ManagementRoot


mgmt = ManagementRoot('192.168.5.110', 'admin', 'xt32112300')
for i in mgmt.tm.gtm.pools.a_s.get_collection():
    for j in mgmt.tm.gtm.pools.a_s.a.load(name=i.name, partition='Common').members_s.get_collection():
        if hasattr(j, 'disabled'):
            print('type A gtm pool name {} member name {} has already been disabled and its fullpath is {}'.format(
                i.name, j.name, j.fullPath))
result:

type A gtm pool name gslb_pool_ctc_v4 member name vs_ctc has already been disabled and its fullpath is /Common/DC-2-GTM-ipv4:/Common/vs_ctc

Process finished with exit code 0

here is the code to enable or disable gtm pool member:

gtm_pool_obj = mgmt.tm.gtm.pools.a_s.a.load(name='gslb_pool_ctc_v4')

mem_ctc = gtm_pool_obj.members_s.member.load(name='/Common/DC-2-GTM-ipv4:/Common/vs_ctc')
"""enable gtm pool member vs_ctc"""
mem_ctc.disabled = False
mem_ctc.enabled = True
mem_ctc.update()

mem_cuc = gtm_pool_obj.members_s.member.load(name='/Common/DC-2-GTM-ipv4:/Common/vs_cuc')
"""disable gtm pool member vs_cuc"""
mem_cuc.enabled = False
mem_cuc.disabled = True
mem_cuc.update()
