Release Notes for the Cisco NSS4000 and NSS6000 Maintenance Release, Version 1. 1 4

CSCsw86202
When rebuilding a RAID1 spare device, the rebuilding does not resume after
the NSS reboots. After reboot, the array might be falsely marked as clean
and the drive falsely marked as synced. This does not affect the initial
rebuild of an array following a RAID creation.
The workaround is to not reboot the NSS during the RAID rebuild.
•
CSCsw86224
If power is interrupted when rebuilding a RAID array (RAID1, RAID5 or
RAID10), the rebuild does not restart automatically after the system is
powered up again.
When this occurs, the array remains in the degraded state and the rebuilt
drive is ejected from the array.
The workaround is to manually restart the rebuild by adding the ejected
drive back to the array by using the Configuration GUI.
•
CSC86417
When the RAID global spares option is enabled in the Configuration GUI, the
RAID spares are not shared during the RAID array rebuild.
For example: If RAIDA has a hot spare and RAIDB does not, if RAIDB is
degraded while RAIDA is rebuilding, the spare will not transfer to RAIDB
until after RAIDA completes the rebuild.
There is no workaround.
•
CSCsw86481
When a Seagate 1 terabyte (TB) hard drive (model ST31000340AS) is
installed in the NSS, it is not detected by the system on bootup or when
hotplugging the drive.
There is no workaround.
•
CSCsw86488
When Seagate hard drives are installed in the NSS, they can take about 30
seconds to be detected on bootup.
This problem occurs because pin 11 of the SATA power connector is not
connected in the NSS backplane design.
There is no workaround.
