Display label location work sheet
The Display label location work sheet option appears on the Hardware Service
Manager display when the system is in the full or limited paging environment. It
allows you to display current configuration location information. You can also
print a worksheet that shows location information by selecting the print function
on the Label Location Work Sheet display. The work sheet printout contains a field
in which you can enter label information.
The system uses description labels to identify hardware. It is the customer’s
responsibility to configure and assign labels in the system for cables and devices.
The system label must match the (physical) label on the hardware. Prior to a
system upgrade procedure, you can select this option to print the label location
work sheet. Use the work sheet to list the hardware labels and to verify that the
system labels match the hardware labels after the upgrade.
For more information on label locations, see “Work with Hardware Products
(WRKHDWPRD) Command” on page 302.
Device concurrent maintenance
Device concurrent maintenance for internal disk units, internal tape units, and
internal optical units is available on most iSeries Model 270, 50x, 51x, 530, 53S, 6xx,
7xx, 8xx, S20, S30, and S40 systems.
Note: Concurrent maintenance for internal tape units and internal optical units is
not available on the 150, 170, 250, 270, 600, 820, and S10 models.
Device concurrent maintenance provides the capability to power down and remove
a failed disk unit, tape unit, or optical unit. It also provides the capability to insert
and power up a replacement unit or a new unit while the iSeries is powered up
and in use. For a configured disk unit device, this concurrent maintenance action is
allowed only when the disk unit device has data storage protection, for example,
when the disk unit is one member of a mirrored pair or is a member of a data
parity array. To determine the storage protection status for disk units on your
server, see “Start Disk Service Here” under “Recovery Procedures” in the Problem
Analysis information for your server. For more information on storage protection,
see the Backup and Recovery, SC41-5304-06 book. This function is also available for
nonconfigured units without storage protection.
