Verifying SRP
This section describes how to verify SRP functionality and verify SRP host-to-storage connections with
the Element Manager GUI and includes the following sections:

Verifying SRP Functionality
To verify SRP functionality, perform the following steps:
Log in to your SRP host.
Step 1
Create a disk partition.
Step 2
The following example shows how to partition a disk by using approximately half of the first SRP disk:
host1# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 8200.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-8200, default 8200): 4000
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Create a file system on the partition.
Step 3
The following example shows how to create a file system on the partition:
host1 # mke2fs -j /dev/sdb1
mke2fs 1.35 (28-Feb-2004)
Filesystem label=
OS type: Linux
