The utility requires startup configuration file with a few cluster-\n\
specific parameters which usually don't change until the cluster is\n\
reconfigured by the system administrator. For example:\n\
\n\
$ cat $HOME/.c0appz/c0cprc/client-22\n\
HA_ENDPOINT_ADDR = 172.18.1.22@o2ib:12345:34:101\n\
PROFILE_FID = 0x7000000000000001:0xcfd\n\
M0_POOL_TIER1 = 0x6f00000000000001:0xc74 # tier1-nvme\n\
M0_POOL_TIER2 = 0x6f00000000000001:0xc8a # tier2-ssd\n\
M0_POOL_TIER3 = 0x6f00000000000001:0xca5 # tier3-hdd\n\
LOCAL_ENDPOINT_ADDR0 = 172.18.1.22@o2ib:12345:41:351\n\
LOCAL_PROC_FID0 = 0x7200000000000001:0x645\n\
\n\
c0cprc is the utility name (c0cp in this case) + rc suffix.\n\
client-22 is the client node name where the utility is run.\n\
HA_ENDPOINT_ADDR is the address of HA agent running on the node.\n\
LOCAL_ENDPOINT_ADDRx and LOCAL_PROC_FIDx addresses and fids are\n\
allocated by system administrator for each user's application\n\
working with the object store cluster.\n\
The easiest way to generate this file is like this:\n\
\n\
$ cd ~/m0client-sample-apps\n\
$ make c=22 sagercf\n\
\n\
Where 22 is the last byte in the client's node IP address.\n";
