RS6000 SSA Raid question

Hi Can I add disks on the fly to extend the capacity of an existing RAID 5 volume? It's created on a 4P Advanced SSA Raid Adapter. I need to extend a volume group, so I figured it would be easiest to extend the "physical disk" which is a RAID5 volume. Thanks.

ssa performances

Helo: We updated form AIX 4.3.3 to AIX 5.1-7 and after this we spent more than double time in read from external disks. Aparently the ssa cards microcode is at last level and all the ptf and apars are instaled. Out backups expent more than double time, but curiously in read only, if we write in...

Problem with a SSA drive

I've a problem with an IBM StorageWorks - Seagate SSA drive, model ST373453LC (IBM P/N 24P3733, Type S53D073, 72,8 GB 15K - USCSI 4 - 320 SSA). I bought this disk used but working; it came from an unknown IBM SSA storage array. I've removed the SCA - SSA adapter (IBM 18P3051 - 001 - R0) and i tried...

SES(4)							   BSD Kernel Interfaces Manual 						    SES(4)

NAME

     ses -- SCSI Environmental Services Driver

SYNOPSIS

     ses* at scsibus? target? lun?

DESCRIPTION

     The ses driver provides support for all SCSI devices of the environmental services class that are attached to the system through a supported
     SCSI Host Adapter, as well as emulated support for SAF-TE (SCSI Accessible Fault Tolerant Enclosures).  The environmental services class gen-
     erally are enclosure devices that provide environmental information such as number of power supplies (and state), temperature, device slots,
     and so on.

     A SCSI Host adapter must also be separately configured into the system before a SCSI Environmental Services device can be configured.

IOCTLS

     The following ioctl(2) calls apply to SES devices.  They are defined in the header file <scsipi/ses.h> (q.v.).

     SESIOC_GETNOBJ	Used to find out how many SES objects are driven by this particular device instance.

     SESIOC_GETOBJMAP	Read, from the kernel, an array of SES objects which contains the object identifier, which sub-enclosure it is in, and the
			SES type of the object.

     SESIOC_GETENCSTAT	Get the overall enclosure status.

     SESIOC_SETENCSTAT	Set the overall enclosure status.

     SESIOC_GETOBJSTAT	Get the status of a particular object.

     SESIOC_SETOBJSTAT	Set the status of a particular object.

     SESIOC_GETTEXT	Get the associated help text for an object (not yet implemented).  SES devices often have descriptive text for an object
			which can tell you things like location (e.g, "left power supply").

     SESIOC_INIT	Initialize the enclosure.

FILES

     /dev/sesN	    The Nth ses device.

DIAGNOSTICS

     When the kernel is configured with DEBUG enabled, the first open to an SES device will spit out overall enclosure parameters to the console.

SEE ALSO

     getencstat(8), sesd(8), setencstat(8), setobjstat(8)

HISTORY

     The ses driver was written for the SCSI subsystem by Matthew Jacob.  This is the functional equivalent of a similar driver available in
     Solaris, Release 7.
