HP StorageWorks 2012sa Modular Smart Array firmware release notes Version J300P10-01 (508849-001, November 2008)
Disable NTP on both controllers, set the IP address of the intended NTP ser ver, an d re-enable NTP.
• When a controller is powered off or in a failed state, the Link LED remains ON although the host
indicates a link down state.
Disregard the Link LED when the controller removal LED is illuminated.
• On the Storage M anagement Unit (SMU) Manage > Scheduler page, the Snapshot Prefix field
allows up to 31 characters to be input but then displays an error m essage indicating the prefix
can have 1-14 chara cters.
Onlytype1to14charactersintheSnapshot Prefix field.
• On Linux, a scan may be required to detect a newly presented Volume/LUN.
A Volum e/LUN newly presented to a Linux host may not be detected by the Linux operating
system. This is a Linux issue, not an array issue. A Linux scan can be used to force detection of
the newly presented Volume/LUN.
The scan c ommand syntax is:
echo “<Channel> <Target identifier> <LUN>“ > /sys/class/scsi_host/
host<Host number>/scan
Where <Channel>, <Target identifier>,and<LUN> can have a - wild card; <Host
number> canbe0,1,2,or3.
Examples
• echo “- - –” > /sys/class/scsi_host/host1/scan # scan all Channels, all
Targets, and all LUNs of Host 1.
• echo “0 - –” > /sys/class/scsi_host/host1/scan # scan Channel 0, all
Targets, and all LUNs of Host 1.
• echo “0 0 –” > /sys/class/scsi_host/host1/scan # scan Channel 0, Target
0, and all LUNs of Host 1.
• echo “0 0 0” > /sys/class/scsi_host/host1/scan # scan Channel 0, Target
0, and LUN 0 of Host 1.
NOTE:
For multipath/dual HBA configurationsconnectedtothesamearray,runthesamecommandfor
both HBAs. For example:
nl
echo “- - –” > /sys/class/scsi_host/host1/scan
nl
echo “- - –” > /sys/class/scsi_host/host2/scan
For HPDM Multipath configuration, after running the sc an command, run the following commands to
update the multipath maps in the kernel:
nl
/etc/init.d/multipathd restart
nl
/sbin/multipath —v3
