Displaying Security strength for management modules and BMC
Setting Security strength for management modules and BMC
Note:
• When Security strength is set to high for the management module, only
TLS 1.2 is enabled. You need OS and Web browser that support TLS 1.2.
See HCSM instruction manuals for the operation.
• If Security strength is set to high for the management module when
HTTPS is disabled, note that the following features are not available.
- Web console
- HCSM
- Hi-Track
• Security strength for the management module can be changed only when
all server blades have been initialized and powered off, and all
management modules have been also initialized.
• Changing Security strength for the management module will restart all
management modules. Then, the new setting value will take effect. For
BMC, the new setting value will instantly take effect without restart.
• Security strength setting for BMC is not supported by CB 520H A1/B1, CB
520A A1, and CB 540A A1/B1.
• If you specify [High] for the security strength setting of a management
module, use Internet Explorer to connect to the Web console of the
management module.
To use Firefox to connect to the Web console of a management module,
specify the default security strength setting for the management module.
• Security strength setting for BMC is supported by the following firmware
versions.
- Management module
A0170 or later
- Server blade
CB 520H B2 with firmware version 04-22 or later
• Security strength setting for BMC is not taken over at N+M cold standby
failover. When configuring N+M cold standby, set the same BMC Security
strength to both the active and standby server blades.
• Management tools connected to the management module via SNMP
v1/v2c are not available when Security strength is set to high for the
management module.
• For LPAR manager mode, a management module and LPAR manager
internally communicate with each other over the management network
using Hitachi protocol. The communication uses cleartext even if Security
strength is set to high for the management module.
