DELL EqualLogic PS6100 uses a virtual ISCSI SAN array to bring enterprise-class features, intelligence, automation and reliability to remote or branch office, departmental and SME storage deployments, supporting VMware, Solaris, Linux, Mac, HPux, AIX, and supporting all operating systems with industry-standard iscsi initiator, while providing a full set of enterprise-class data protection and management features, reliable performance, scalability and fault tolerance Is the starting point for medium-sized enterprise-class storage.

DELL EqualLogic PS6100 details:

Upper layer application basic configuration:

The storage can be initialized by connecting the serial port.

Log in to the configured ip address through the browser. The account defaults to grpadmin and the password defaults to grpadmin;. You can also log in through the serial port to view the status.

Partition and access of volumes:

Underlying structure:

Take 9 disks as an example. When dell eq creates a RAID, it allocates a hot spare by default. There is only a hot spare in the chassis, not a global hot spare.

A group of RAID5 is composed of 8 disks, and the 15m size is divided into a block from the RAID5. All 15m blocks are put into a storage pool and redistributed from the storage pool. The storage pool can be reassembled into Mdisk across arrays and mapped to different hosts.

Combination method, as shown in the following figure:

Figure 3:

15m blocks are arranged and combined according to the bitmap information in Vdisk. Many 15m blocks are combined into one or several Mdisk, and the Mdisk is assigned to the host and the file system is created.

Bitmap information, as shown below:

General fault information collection:

The general problem is that there is a problem with the hard disk or the controller, resulting in the storage cannot be accessed.

After a problem occurs, you can first connect with the serial port, check the status of the hard drive, and confirm that there is a problem with the hard disk. The command is as follows:

# raidtool-Z

# raidtool-z

# diskview-j

Figure 6:

And collect log information through the network port and analyze it. The command is as follows:

Telnet-f c:\ eqlog.txt groupIP

Su exec bash

Uname-a

Ifconfig-a

Diskview-j

Diskview-Q

Dmesg

Rstat

Dbtool

Eqllogmgr-r

Figure 7:

After grabbing the log file for analysis, before other operations, all the hard drives should be backed up to prevent the subsequent operation from being irreducible. The security of the original storage media should be ensured and subsequent recovery operations should be carried out.
