Troubleshooting

9–70

When this happens, the SFS service prints a message similar to the following in the

/var/

log/messages

file:

sfsmount: Waiting for IB to be ready.

If this state persists for a long time, investigate the InfiniBand network. (You can log in and

run the

vstat

command to confirm the port state.)

If some of the services are in the

recovering

state, the mount operation may be delayed for

any of the reasons described above (for the scenario where all file systems are in the

running

state). In addition, Lustre may reject requests because the

recovering

state requires all client

nodes to be actively connected before continuing. If any client node fails to connect (for

example, because it has been rebooted or remains down), Lustre must wait for up to 10 minutes

before timing out the recovery operation.

In such a situation, you will see that not only is the node that is currently being booted failing to

connect, but that other nodes (that were not rebooted) are also not connected. This is a normal

process in Lustre and you must be patient. Specifically, do not reboot any of the HP SFS servers;

if you do so, the 10-minute timeout period will restart.

9.43 Recovering after using the ifdown command

If you use the

ifdown

command on the site network or Gigabit Ethernet interconnect on the server that is

running the administration service (usually the administration server), the alias IP address on the network

stops working. This means that access to the LDAP database fails.

To restore the alias IP address functionality, run the

configure server

command on the server that is

running the administration service.

9.44 Password needed for ssh access

Normally, you do not need to supply a password to log in to an Object Storage Server from the

administration server. However, if an Object Storage Server is in the

not-configured

state, you must

supply a password when you log in to the server.

There are two main reasons why a server may be in the

not-configured

state when you attempt to log

in, as follows:

You logged in too early, and the server is still in the process of being configured. Wait a few minutes

and then attempt to log in again.

A failure is preventing the configuration process from completing. Use the

show server

server_name

command to determine the cause of the failure. When you have corrected the

problem, reboot the server.

9.45 The syscheck command reports that the Insight Manager Agents

are not running

The

syscheck

command may report a warning message similar to the following:

south3 Insight Manager Agents (hpasm) not running.

If this happens, you can correct the problem by logging in to the server and running the following

commands:

# service hpasm stop
# service hprsm stop
# service hprsm start
# service hpasm start
# service lsmon_scripts restart
