Description
Default: No
This field applies to volumes that are already initialized, if a specific format template is not specified. Enter Yes to reinitialize the disk with defaults calculated internally by the Format Disk command. If you enter No or leave this field blank, the disk is reinitialized with its current parameters.
Default: All available disk space
This parameter applies to disks on Series 5000
workstations only. Enter a size for the eTOS partition, in M bytes. (Unless you plan to install MS-DOS on the Series 5000 workstation, you can leave this field blank.
See the GTOS Executive Reference Manual for more information aoout disk partitioning.)
Many sizes and types of disks are available for the SRP. Unlike work-station disks, SRP disks are not packaged in modules. They can be installed within an SRP cabinet, or they can be external to the system.
In some cases, the system administrator is responsible for installing disks; in other cases, disks are installed by a field service engineer. If you need information about installing disks, see the installation guide for your SRP.
Disk Compatibility
On an SRP, different types of disks are compatible with different proces-sors, as described below:
• SCSI disks are connected to a General Processor with SCSI Interface (GP+SI).
• Non-SCSI ST-506 disks are connected to a File Processor (FP).
• Non-SCSI SMD disks are connected a Data Processor (DP).

Device Names for SRP Disk Drives
11-8
The operating system assigns default device names for disk drives controlled by the master processor only. If the master processor is a GP+SI, default disk device names are dl through d15 (see the XE-530 Shared Resource Processor Hardware Installation Guide). On FP master processors, defaults are dl through d3. Because a QIC tape drive
occupies the first drive slot (as shown in Figure 11-2), there is no disk drive named dO on an SRP. If the master processor is a DP, default device names are sO through s5.
Disks connected to a processor other than the master processor must be named in the operating system configuration file. See Section 17,
"Configuring Shared Resource Processor Operating Systems," for information about assigning device names.

Initializing a New SCSI Disk
To initialize a new SCSI disk on an SRP, follow these steps:
CAUTION
The following procedure destroys all data on the disk.
1. On the Executive command line, type Administrator Cluster View;
then press RETURN.
2. Fill in the command form, as shown in the following example. (See Table 4-1 for a description of parameter fields.)
Administrator Cluster View [Processor name - XE only]
[User name]
[User file password]
[Node name]
[Old XE run file?]
[Run file to invoke]
[Partition size]
3. Press GO.

4. Ifnecessary, start the Executive by signing on or exiting the application that is running.
5. On the command line, type Format Disk; then press RETURN.

Initializing New ST·506 or SMD Disks
To initialize a new ST-506 or SMD disk, you need to know the manufac-turer and size of the disk. In addition, you need the bad spot report, which is usually packaged in a plastic pocket attached to the disk-drive housing.
The following sections describe how to create a bad spots file and how to identify the device template for an ST -506 or SMD disk.
Creating a Bad Spots File
11-10
To create a bad spots file, you use the Editor application, as described in the following procedure.
1. On the Executive command line, type Editor; then press RETURN.
2. Type a file specification for the bad spots file, as shown in the following example; then press GO.
File name(s) [ISys]<Sys>BadSpots d2
Adding Hard Disks
3. Enter the list of bad spots, as described in "Bad Spot Formats,"
below.
4. When you have finished entering bad spots, press FINISH, then Go, to save the file.
Bad Spot Formats
Enter bad spots in one of the following formats. See the documentation for the disk to determine which one to use.
e/h/sb/be e / h / #seetor e / h / $seetor where
e h sb be
#seetor
$seetor
Is the cylinder number.
Is the head number.
Is the starting byte number.
Is the number of bits in error.
Is the sector number of a 512-byte sector.
Is the sector number of a 256-byte sector.
Leave a space between each bad spot entry, as shown in Figure 11-3.

Identifying the Device Template
To format a new ST -506 or SMD disk, you must specify a device template in the Format Disk command form. Device template names are derived from the manufacturer and size of the disk, for example, Maxtor53. To identify the correct device template for your disk, see Table 11-2. If a device template is not listed for your disk, see "Adding a Device Template," later in this section.
Initializing the Disk
11-12
To initialize a new ST-506 or SMD disk on an SRP, follow these steps:
CAUTION
The following procedure destroys all data on the disk.
1. Start an Administrator Cluster View session, as described for SCSI disks, earlier in this section.
2. On the Executive command line, type Format Disk; then press RETURN.
3. Fill in the command form, as shown in the following example. (See Table 11;.1 for a description of parameter fields).
