Question
What data needs to be collected to debug why AIX LPAR or VIOS does not have network connectivity?
Answer
When AIX LPAR or VIOS does not have network connectivity, snap can not be transferred out of the host and upload to IBM. In this condition, login to partition (i.e. LPAR or VIOS that does not have network connectivity) using HMC console and collect data using following steps and send to IBM.
(1) Login to HMC using SSH (port 22) using terminal software (e.g. PuTTY) with logging enabled. Figure 1 and 2 show how to select connection type SSH and session logging respectively.
Figure 1
Figure 2
(2) Open vterm session to login to the problematic partition.
$ mkvterm -m <managed system> -p <Partition name of LPAR or VIOS>
Note: On LPAR login as root and on VIOS login as padmin and run "oem_setup_env" to change to root.
(3) Run following commands.
# oslevel -s
# /usr/ios/cli/ioscli ioslevel (on VIOS only)
# emgr -lv3
# lppchk -c
# lsattr -El sys0
# lsdev -Cc adapter
# lsdev -Cc if
# ping -c 5 <default gateway IP address>
# ifconfig -a
# netstat -s
# netstat -in
# netstat -rn
# arp -an
# netstat -v
# errpt -a
(4) Send putty.log to IBM.
(5) If VIOS has an IP Address configured and does not have network connectivity then repeat step 3 and 4 on primary VIOS and backup VIOS.
(6) If VIOS has the network connecvity then collect snap using following steps instead of step 3 and 4.
(a) login to the primary VIOS as padmin user and run following command.
$ snap
$ snap
(b) Rename the file snap.pax.Z created in the padmin home directory to include the hostname.
$ mv snap.pax.Z <hostname>.snap.pax.Z
$ mv snap.pax.Z <hostname>.snap.pax.Z
(c) Send <hostname>snap.pax.Z to IBM.
(d) Repeat steps (a), (b) and (c) on backup VIOS.
(7) Send data to IBM.
