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
■
embedded 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 embedded 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 embedded SMU on the replacement node, but it is recommended to fully
uninstall the embedded 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
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 manually. The data and file systems will remain intact
independent of the replacement and without a backup.
Note: Replacement servers are shipped without an embedded system
management unit (SMU), so you must have a SMU installed before you can
connect to a standalone server.
Important: Set expectations up front with the customer that this will delay
time to recovery, and that some aspects of the systems configuration might
never be recovered.
Obtaining backups, diagnostics, firmware levels, and license keys
On the old server:
Hitachi NAS Platform 3080 and 3090 G2 Hardware Reference
Note: SMU iso images can be downloaded from Support Connect.
