Servers - SSA RAID adapter restricted to RAID 5 with over 2GB of RAM
Applicable to: World-Wide
Source: RETAIN tip H165049
SYMPTOM:
System crash (including NT bluescreen or NetWare abend), system hang, garbled video, other unpredictable results.
PROBLEM ISOLATION AIDS:
- The system is any PC Server, Netfinity Server, or OEM Intel Server which supports SSA.
- The system is configured with one or more of the following SSA adapters:
- Option P/N 32H3811, FC4011, or FRU 32H3811.
- Option P/N 96H9835, FC4012, or FRU 02L7644.
- The system uses one or more of the following capabilities of the SSA adapters:
- JBOD (single disks), RAID 0, and/or RAID 1 on Option P/N 32H3811, FC4011, or FRU 32H3811.
- JBOD and/or RAID 1 on Option P/N 96H9835, FC4012, or FRU 02L7644.
- The system has more than 2GB of supported RAM installed.
Systems which currently support both SSA and more than 2 GB of RAM include:
- IBM Netfinity 7000 and Netfinity 7000 M10
- Compaq ProLiant 5000 and ProLiant 6000
- HP NetServer LX Pro and LXr Pro
(note: Support of SSA on non-IBM hosts requires Windows NT)
- The system is using one of the following Network Operating Systems:
- Windows NT
- Novell NetWare and intraNetWare
- OS/2
- Diagnostics pass.
FIX:
This restriction will be removed in a future SSA RAID adapter.
WORKAROUND:
- For the IBM SSA RAID Adapter for PC Servers (32H3811 / FC4011 / FRU 32H3811), restrict use to RAID 5 or reduce server memory to 2 GB.
- For the IBM SSA RAID Cluster Adapter (96H9835 / FC4012 / FRU 02L7644), reduce server memory to 2 GB.
DETAILS:
A 2 GB memory limit shall be observed on all servers with the IBM SSA RAID Adapter for PC Servers (except RAID 5 use) or IBM SSA RAID Cluster Adapter installed. On server systems with greater than 2 GB of memory installed, the use of either:
1) JBOD (single disks), RAID 0, or RAID 1 on the SSA RAID Adapter for PC Servers,
-- or --
2) JBOD or RAID 1 on the SSA RAID Cluster Adapter will cause unpredictable results and is not supported by IBM.
