16.
Adding unit above
This issue has been resolved for most cases. If there is an
non-partitioned R5 set and
error noted when this is attempted, refer to the
receiving Error 1170:
REINITIALIZE command in the HP StorageWorks
Partitions found on
HSG60 and HSG80 Array Controller and Array
container, unit not
Control er Software Command Line Interface Reference
created.
Guide for help.
17.
Using the RUN CONFIG
The RUN CONFIG command has been improved and
command while bad disk drives now skips bad disk drives after the command is submitted
exist and LFC 83030100
and completes its routine. Previously, the controller would
fail with LFC 83030100. The system reports the following
diagnostic error information:
DEVICE AT P1:T4:L0 failed
initialization, Skipping Device
18.
Controller failure and LFC
With previous ACS versions, controller restarts that
44650100
resulted in the issuance of LFC 44650100 occurred if the
controller encountered certain workloads (for example,
large writes outstanding to the controller). This issue is
resolved.
19.
Device error handling
ACS has been improved to better handle device errors
and inconsistent drive behavior. ACS more readily ejects
drives under failure conditions to the failedset if the
container is redundant.
20.
Spontaneous controller restarts
Control er restarts attributed to Intel i960 processor, PCI
on snapshot
Data or Address Line (PDAL), and Cache Data and
Address Line (CDAL) events occurred if heavy I/O load to
source units of a snapshot existed. This issue is resolved
with this release.
21.
Intermittent LUN failures
Under some conditions, LUNs failed to respond to SCSI
inquiries. This issue is resolved with this release.
22.
Controller port TACHYON chip With earlier versions of ACS, controller port TACHYON
malfunction
chip lock-ups occurred. Issuing the DISPLAY HOST
Virtual Terminal Display (VTDPY) command, in some
cases, reset the port. With this release, ACS employs an
automatic port reset.
23.
Excessive abort messages
Under excessively high I/O rates, which included large
logged by the host
transfers, host systems occasionally aborted previous work
queued to the controller due to considerable control er
activity. This issue was further complicated by the use of
partitioned containers and path switches. With this
release, host systems initiate a fewer number of aborted
I/Os.
