But now, I would install the snmp agent of my RAID controller.
I used the rpm and I convert it ina deb with alien :

# dpkg -i sas-snmp_17.05-3_amd64.deb

Starting snmpd
/etc/lsi_mrdsnmp/sas/install: 182: [: 0: unexpected operator

Starting LSI SNMP Agent
/etc/lsi_mrdsnmp/sas/install: 210: [: 0: unexpected operator
Starting LSI SNMP Agent:
/etc/init.d/lsi_mrdsnmpd: 153: /etc/init.d/lsi_mrdsnmpd: daemon: not found

I edited /etc/init.d/lsi_mrdsnmpd to resolve the problem of the daemon command by replacing it by :

....
${agent} -c ${SNMPDCONF}
#daemon ${agent} -c ${SNMPDCONF}
....

Moreover, I added a symbolic link to solve a problem of library :

/usr/lib/libsas_objects.so -> /usr/lib64/libsas_objects.so.1

But now, when I try to start the service :

# ./lsi_mrdsnmpd start
Starting LSI SNMP Agent:
LSI MegaRAID SNMP Agent Ver 3.18.0.5 (Oct 30th, 2012) Started

I don't have nothing in a ps command. And if I verify the syslog log, I have :

Oct 16 16:43:45 Server1 MegaRAID SNMP AGENT: Error in getting Shared Memory(lsi_mrdsnmpmain)

If I try to execute manually the command :

# ./lsi_mrdsnmpagent -c /etc/snmp/snmpd.conf
LSI MegaRAID SNMP Agent Ver 3.18.0.5 (Oct 30th, 2012) Started

Same result on the syslog.

I tried to strace the start of the service :
Here th eend of the strace :

But now, I'm blocked and i don't know to resolve this problem, have you got an idea of that ?

Thanks,

EDIT

Well, today the service is running :

root     16777     1  0 16:35 ?        00:00:00 /etc/lsi_mrdsnmp/lsi_mrdsnmpagent -c /etc/snmp/snmpd.conf
root     16778 16777  0 16:35 ?        00:00:00 /etc/lsi_mrdsnmp/lsi_mrdsnmpagent -c /etc/snmp/snmpd.conf

youpi!!!

But…when I try to pass a OID to the agent via lsi_mrdsnmpmain it returns nothing and the result code is 1 :

# /usr/sbin/lsi_mrdsnmpmain -g .1.3.6.1.4.1.3582.5.1.1.0
# echo $?
1

I strace the service lsi_mrdsnmpagent and I can read that each time i try lsi_mrdsnmpmain:

futex(0x7f61f938e000, FUTEX_WAIT, 0, NULL) = 0
write(1, "####INSIDE GET#####\n", 20)   = -1 EBADF (Bad file descriptor)
futex(0x7f61f938e020, FUTEX_WAKE, 1)    = 1
futex(0x7f61f938e000, FUTEX_WAIT, 0, NULL) = 0
write(1, "####INSIDE GET#####\n", 20)   = -1 EBADF (Bad file descriptor)
futex(0x7f61f938e020, FUTEX_WAKE, 1)    = 1
futex(0x7f61f938e000, FUTEX_WAIT, 0, NULL) = 0
write(1, "####INSIDE GET#####\n", 20)   = -1 EBADF (Bad file descriptor)
futex(0x7f61f938e020, FUTEX_WAKE, 1)    = 1
futex(0x7f61f938e000, FUTEX_WAIT, 0, NULL

And if i strace lsi_mrdsnmpmain I obtain:

15:41:36 rt_sigaction(SIGRT_1, {0x7fe5257a8a40, [], SA_RESTORER|SA_RESTART|SA_SIGINFO, 0x7fe5257b1890}, NULL, 8) = 0
15:41:36 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0

15:41:36 shmget(0x884b9, 1024, 0600)    = 131072
15:41:36 shmat(131072, 0, 0)            = 0x7fe525bdc000
15:41:36 futex(0x7fe525bdc000, FUTEX_WAKE, 1) = 1
15:41:36 futex(0x7fe525bdc020, FUTEX_WAIT, 0, NULL) = 0
15:41:36 shmdt(0x7fe525bdc000)          = 0
15:41:36 exit_group(1)                  = ?
15:41:36 +++ exited with 1 +++

If you have ideas about the EBADF (Bad file descriptor) or ideas to access mib…

Thanks !
