Upgrades
Replacement servers can be down or above a revision, and not at the
expected level of firmware required at the customer site. An upgrade is
typically required during the replacement process, which is not covered in
this document. It is assumed that all services personnel performing a
replacement have already been trained, and know where to get this
information within their respective organization.
Manually installing an internal SMU (if necessary)
HNAS 3080/3090 spare or replacement units are shipped without the internal
SMU installed.
Before you begin
The SMU software will need to be manually installed in the following case:
• If the HNAS (all versions) is a spare/replacement and the field installer
requires the internal SMU to configure the replacement prior to adding to a
cluster (or replacing a single node that has no external SMU). However,
once added to the cluster, the internal SMU should be uninstalled.(
smu-
uninstall
from the CLI of the newly added node). Note, when added to a
cluster, the external SMU will disable the internal SMU on the replacement
node, but it is recommended to fully uninstall the internal SMU.
Procedure
1. Obtain a copy of the SMUsetup .iso file and copy the file into
/tmp
scp /tmp/SMUsetup.iso
2. As 'root' on the node:
cd /tmp
mount –o loop SMUsetup.iso /mnt/cdrom
/mnt/cdrom/autorun
Note: SMU iso images can be downloaded from TISC or the
support portal.
Replacing a single server with an embedded SMU
If a single server with an embedded SMU is non-functioning, and does not
have a recent backup saved off platform, then a challenging and manual
recovery process is necessary. If this circumstance is encountered, call the
support organization for a copy of the system's latest diagnostics files. If
available, these files can be used as a guide in reestablishing the system
